YSK that at-home IPL devices require long-term consistency before you notice results

A lot of people try at-home IPL (intense pulsed light) devices expecting quick results, but these devices are designed to work gradually over multiple sessions rather than immediately.

Why YSK:

Because many people stop using them too early and assume they don’t work. Most at-home IPL devices are meant to be used on a schedule over several weeks or months before any noticeable reduction in hair growth happens.

For example, I started using an at-home device (the Wavytalk IPL Hair Removal Device) and realized the instructions emphasize consistency more than anything else. Missing sessions or using it irregularly can make it seem like nothing is happening.

Understanding that these devices rely on repeated use helps set more realistic expectations and prevents people from giving up too early.

LPT: Fix one small inconvenience in your life every single day

Just one thing - no matter how stupid or small. It’s the little stuff you’ve been tolerating forever.

Reorganize the drawer you curse at every time you need a pan. Dust one thing that’s been bothering you every time you look at it. Set up autopay on that one bill. Move the thing you keep tripping over or hate to see put everyday. Change the batteries in the thing that keeps beeping at you. Reorganize the drawer you curse at every time you need a pan. Rearrange where things in the refrigerator so it makes the most sense to you and nothing spoils.

If it feels too big, just do one part of it. Wipe one shelf in the fridge. That’s it. You’ll probably keep going, but if you don’t - that still a win baby!

I had an automatic trash can that beeped at me constantly for months. Finally took the batteries out. Now every time I walk past it I’m like…hell yeah.

You’d be surprised how much lighter your day feels when your environment just stops annoying you.​​​​​​​​​​​​​​​​

YSK that major pharmacy chains are charging your insurance more for prescriptions than the cash price, and you can check this before paying

I found this out the hard way last month when I picked up my generic blood pressure medication. My insurance copay was $47. On a whim, I asked the pharmacist what it would cost without insurance. $12.

\*\*Why YSK:\*\* Pharmacy Benefit Managers (PBMs) negotiate prices between insurance companies and pharmacies, and sometimes those negotiated rates are actually higher than the cash price. You're legally allowed to ask for the lower price, but most pharmacies won't volunteer this information because they make more money from your insurance company.

This is especially common with generic medications. The system is set up so that when you hand over your insurance card, the pharmacy runs it through and tells you your copay. What they don't tell you is whether that copay is higher than just paying out of pocket. And here's the infuriating part: some insurance plans have "gag clauses" that actually prevented pharmacists from telling you about cheaper options until laws started changing in 2018. Even now, most won't mention it unless you specifically ask.

I started checking every prescription. Out of my last 6 medications:
\- Lisinopril: $47 copay vs $12 cash
\- Omeprazole: $30 copay vs $9 cash
\- Metformin: $25 copay vs $4 cash

That's $76 in savings on just three medications in one month.

\*\*How to check:\*\*

When picking up a prescription, simply ask: "What would this cost without insurance?" The pharmacist has to tell you. If the cash price is lower, tell them you want to pay that instead. You can also check prices ahead of time using GoodRx or RxSaver apps, which show cash prices at different pharmacies near you.

The catch: if you pay cash price, that money typically won't count toward your insurance deductible. So you need to decide whether the immediate savings outweigh the deductible credit. For me, with a $6,000 deductible I never hit anyway, the cash price wins every time.

Some pharmacies are worse than others about this. CVS and Walgreens have been particularly bad in my experience. Costco pharmacy (you don't need a membership to use it) consistently has the lowest cash prices and their pharmacists seem more willing to mention it.

The whole system feels designed to extract maximum money from people who are just trying to stay alive. I'm still angry that I probably overpaid for years without knowing. Someone on ADHDerTips mentioned this practice affecting their ADHD medication costs too, which makes sense given how expensive those can be even with insurance.

YSK about Psychological Reactance, the impulse to resist and do the opposite of what you're told, even if you agree with it

You Should Know about the concept of Psychological Reactance. It's a well-documented psychological phenomenon where, upon perceiving that someone is trying to limit your freedom of choice, you feel an immediate, often unconscious, urge to resist.

This isn't just about disagreeing. It's the stubborn, automatic "don't tell me what to do" impulse that can pop up even when the advice is good or the request is reasonable.

Examples:
* A doctor tells you to stop eating a certain food, and suddenly you crave it more than ever.
* A pop-up on a website aggressively demands you subscribe, and your immediate instinct is to close the tab.
* Someone tells you "You have to watch this show!", and your interest instantly drops.

This happens because our brains are wired to protect our sense of autonomy. When we feel that autonomy is threatened, our primitive, emotional brain triggers a defensive reaction before our rational brain has a chance to evaluate the situation logically. It's a defense mechanism that prioritizes freedom over logic.

**Why YSK:**

Understanding reactance gives you a massive advantage in your daily life. When you feel that spike of internal resistance, you can learn to recognize it not as a genuine opinion, but as an automatic reaction.

By pausing and identifying "Ah, this is reactance," you create a small space between the impulse and your action. In that space, you can ask yourself: "Am I resisting because this is a bad idea, or am I resisting simply because I feel pushed?"

This awareness allows you to reclaim your power of choice. You can then make a decision based on your own rational assessment, not on a primitive, automatic impulse. It's the difference between being controlled by your reactions and being in control of your decisions.

YSK Amazon will switch subscriptions to another card on your account if payment fails instead of pausing your subscription.

Why YSK.

If you are trying to clean up your finances by cancelling cards or giving them spending limits, Amazon will still try to take your money through any other listed payment system on your account instead of pausing the subscription.

This can cause you overdraft fees or other issues like fraud alerts when Amazon switches the payments. Particularly if you have used a card to buy items on Amazon, video subscriptions normally appear as ‘Kindle’ charges to your bank, meaning they won’t be immediately recognisable as normal spending on that card.

It’s a common misbelief that cancelling a card will stop the spending associated with it, and then you can ‘see what you’re missing’ when it comes to subscriptions.

YSK your phone number is probably listed on hundreds of “data broker” websites

YSK that if you Google your phone number in quotes like:

"xxx-xxx-xxxx"

you may find it listed on dozens or even hundreds of “people search” or data broker websites.

Why YSK: These sites aggregate public records and other data sources and often list:

\-phone numbers

\-current and past addresses

\-relatives

\-age ranges

Examples include Whitepages, Spokeo, FastPeopleSearch, Radaris, etc.

I recently did this and found my information across a huge number of sites, which likely explains why spam calls increase after a data breach.

You can remove yourself manually, but each site has its own opt-out process and some require identity verification.

If you’ve never checked before, try Googling your own phone number in quotes and see what appears.

YSK that you can disable Google's un-feature of shortening shared links into http://share.google/ URLs

Why YSK: shortened links have several downsides (see below), and Google has chosen to make them the default when sharing links. You may be helping Google track others without noticing it.

According to [9to5google]( https://9to5google.com/2025/06/26/google-app-link-shortener/) and confirmed by me just now, you can go into the settings of your account in the Google app to disable link shortening:

> Open the Google app and tap your profile avatar for Settings. Under “Other settings,” there’s a new “Shorten links to web pages: Links you share to pages will be automatically shortened” toggle. It’s automatically enabled in an unfortunate default behavior.

Shortened links are undesirable for several reasons:
- The receiver of the link can't tell where it goes before clicking. In the worst case, you could be led to a malware or phishing site. You _should_ check a link before clicking it, but link shorteners make this literally impossible.
- Google tracks every click on such a link, even if the receiver doesn't want to use Google.
- It is simply unnecessary, at least in the vast majority of cases.
- Maybe even more important: Google can at any time stop supporting the shortened link. This has happened before, [with http://goo.gl/ links]( https://mashable.com/article/google-discontinuing-link-shortener-how-to-check-yours) (at least some of them).

I'm not under the illusion that stopping using Google's link shortener will prevent Google from tracking people, but this is a "feature" that has no benefit for users, so there's no tradeoff in deactivating it.

LPT - If someone keeps twisting your words, stop explaining. Ask them to repeat your point back in one sentence.

When I feel like I am getting played in a one on one or at work, I stop arguing details.

I say, before I answer, repeat what you think I just said in one sentence.

If they repeat it fairly, we can move forward. If they cannot, or they twist it again, I know they are not trying to understand, they are trying to win.

Then I end it with, cool, we are not aligned, and I walk away.

LPT: Before a difficult conversation, write down the one thing you most need the other person to understand. Not what you want to say — what you need them to understand. It will change how you approach the whole thing.

Most difficult conversations go sideways not because people are unreasonable but because the person talking is focused on what they want to express and the person listening is focused on how to respond, and neither of them is focused on actual understanding. I spent years going into hard conversations with a mental list of things I wanted to say and almost always came out feeling like nothing had landed. The shift for me was a small reframe I picked up from a therapist: before the conversation, write down in one sentence what you genuinely need the other person to walk away understanding. Not your whole case. Not the history. Not the list of things they've done. Just: if they understood one thing from this conversation, what would actually change something? When you know that, your entire approach shifts. You stop trying to cover every point and you start figuring out how to make that one thing land clearly. You cut the things that are true but not useful. You think about what the other person's starting position is and what would actually reach them from where they are rather than from where you are. I've used this before conversations with my partner, my manager, my parents, and once with a landlord who was trying to keep my deposit. In every case the conversation was shorter and more productive than my previous approach. You might not get the outcome you want, but you have a much better chance of being genuinly heard, which is usually what the outcome depends on anyway.

YSK about the "Method of Loci" (or Memory Palace): an ancient mnemonic technique where you associate information with specific locations in a familiar physical space inside your mind

The Method of Loci is a memory enhancement strategy that uses visualizations of familiar spatial environments to recall information. Imagine your own house. To remember a shopping list (milk, bread, eggs), you would mentally "place" each item in a specific spot on a familiar route: a carton of milk spilling on your doormat, a loaf of bread sitting on the living room couch, and eggs smashed against your TV screen. To recall the list, you simply "walk" through your house in your mind and see the items you placed. This technique leverages your brain's powerful spatial memory to organize and retrieve abstract information.

Why YSK: Because this isn't just a trick for memory champions; it's a practical tool anyone can use to improve their memory for studies, presentations, or daily tasks. It demonstrates that memory isn't just a passive storage system, but an active, creative process. Learning this technique can fundamentally change your relationship with your own memory, transforming it from a fallible database into a dynamic, explorable landscape that you can architect yourself. It's a way to build a personal "Foundation" for your knowledge.

LPT: The dumber my productivity system, the better it works

I used to obsess over productivity apps and systems. Downloaded everything, color-coded my entire life, spent weekends perfecting my setup. Then I would ignore notifications and forget the app existed after a week.

So I decided to go completely low-tech. Deleted all productivity apps on my phone. Switched to a sketchbook with just three categories: Urgent, Later, Done.

The rule is simple: if something sits in Later for more than a week, I erase it. Either it gets done or it doesn't matter enough.

A messy notebook performs better than any pristine planner I have ever owned because I actually use it. The dumber the system, the more likely I am to stick with it.

YSK about Solastalgia: the specific form of emotional distress caused by watching your home environment change for the worse around you

Solastalgia is not nostalgia; nostalgia is the homesickness you feel when you are away from home. Solastalgia is the homesickness you feel when you are still at home. It's the pain, grief, or anxiety caused by the negative transformation of your familiar surroundings.
It's the feeling of loss when the forest you grew up playing in is replaced by a shopping mall. It's the quiet dread of seeing your local river dry up year after year. It's the unease of realizing the seasons don't feel the same as they did when you were a child. It's the specific melancholy of losing a home that you haven't even left.

Why YSK: Because it gives a name to a deeply personal and increasingly common form of modern grief. Many people feel this profound sense of loss but struggle to articulate it, sometimes dismissing it as simple sadness or anger. Understanding Solastalgia validates this feeling as a legitimate response to environmental change. It's a shared experience of our time, and knowing the word for it can be the first step toward processing it, both personally and collectively. It's the language for a wound many of us carry without knowing its name.

YSK cancelling Netflix through a third party like T-Mobile doesn't cancel your subscription. You will be charged to the card on file. Refund requests will be denied.

TL;DR If you’re paying for your subscription through a third party company like T-mobile cancelling your subscription with that company does not cancel your actual subscription with Netflix. Any card you have on file will be billed the day after your “cancelled” service ends. T-Mobile doesn’t provide this information and the only way to find it is buried in the help section of http://Netflix.com/. Netflix will only refund the most recent charge regardless of the circumstances.

I have been paying for Netflix through T-Mobile for about a year. Previously my mom was paying for it for through Netflix. I cancelled the Netflix add on with T-Mobile through the T-Life app on January 24th. There was no information about when the service would end, or that the account would still be billed through the card on file in the Netflix account. There were zero warnings, disclosures, or any information at all. Just cancelled. I (wrongfully) assumed we would get a notice on the TV that the subscription has ended when the billing period was over since I had cancelled mid billing cycle with T-Mobile. In January 25th my mom’s credit card was billed for a full month of see. We did not know about this until she looked at her statement today. I immediately logged in on the Netflix website and cancelled the account. When I checked the billing history I saw another charge for February 25th.

I contacted Netflix chat to request a refund. I explained that I was under the impression I cancelled the service in January and was requesting a refund for both charges. Was told there was usage on the account and they could refund only the most recent charge and cancel services immediately. I explained

\> Yes, when I canceled it didn't say when services would end so my mom just kept watching it until it stopped. She saw the charge on her credit card statement today. We can cancel today but l'd still like both charges refunded. The process was unclear and there were no warnings.

And the response was infuriating

\> Apologies \*\*you should have contact us earlier then\*\*, right now only recent charge can be refunded that was deducted on Feb 25, let me know how you wish to proceed?

How was I supposed to contact them with this issue earlier when I contacted them \*\*immediately\*\* after discovering the problem? No explanation would help me resolve my issue. When I asked for my complaint to be escalated to a supervisor I was told the answer would be the same. While waiting for a supervisor I was disconnected from chat.

I decided to call and speak to someone directly to resolve my issue. When I explained what happened I was told I needed to reference a specific section of their \[help FAQs\] ([ https://help.netflix.com/en/node/66915?g=94ab6a64-8c61-40f2-b8a0-7469422f0321&lkid=URL\_SUPPORT\_ARTICLE&lnktrk=EVO](https://help.netflix.com/en/node/66915?g=94ab6a64-8c61-40f2-b8a0-7469422f0321&lkid=URL_SUPPORT_ARTICLE&lnktrk=EVO)) and I would find an explanation for why I was charged there. I understood \*why\* I was charged, \*after the fact\*, I didn’t need further explanation. I was told there was absolutely zero chance of receiving a refund ($18.66) for the previous charge and they were only able to refund the most recent one. The only way I can get that money back is to dispute the charges with my bank.

This is an incredibly unethical, predatory practice and policy. I contacted them within minutes of discovering the charges and their response was I should have contacted them earlier. There was no information provided through T-Mobile at the time of cancellation, no warnings, no disclosures. The information I was supposed to magically know is buried in a long list of information in their help section. A multi-billion dollar company apparently needs their $18 far more than their consumers do. Why YSK: this will prevent you from falling victim to their greed like I did.

If you keep seeing the same position posted every time you open the job app, it could indicate high turnover.

Before accepting an offer, ask directly:
“Is this a new role or a replacement?”
If it’s a replacement, ask why the previous person left.

It’s a simple question that can reveal a lot about team culture, management, and workload.

Pro tip: check out reviews on Glassdoor before you apply. They can reveal things you won’t see in the job description

YSK that free file converter websites like iLovePDF set 637 cookies from 221 domains when you upload a single document

Why YSK: If you've ever converted a PDF, merged documents, or compressed images using a free online tool, your files were likely processed on servers surrounded by dozens of ad networks and tracking scripts. Knowing this helps you make better decisions about which tools you trust with sensitive documents like tax returns, contracts, and resumes.

I audited the privacy practices of popular free file converter sites by inspecting network requests, reading privacy policies, and counting cookies and third-party domains.

iLovePDF: A single page load set 637 cookies from 221 domains. 141 of those domains belonged to ad networks. Your uploaded files pass through servers that are deeply integrated with advertising infrastructure. Their privacy policy states they may share data with third-party partners for advertising purposes.

SmallPDF: Loads Google Analytics, Hotjar (full session recording), and multiple ad trackers before you even upload a file. Their free tier processes files server-side, meaning your documents leave your device and sit on their infrastructure. Privacy policy allows sharing with "service providers and business partners."

CloudConvert: The relative exception. Minimal tracking, transparent pricing model, and files are deleted from servers after conversion. Still server-side processing, but significantly less advertising infrastructure compared to the others.

The pattern across most of these tools is the same: the file conversion is the product you see, but the tracking ecosystem around it is the actual business model. Your documents are being uploaded to servers that are also talking to dozens of ad networks, analytics platforms, and data brokers.

For anything sensitive, converting files locally on your own machine is the safest option. LibreOffice handles most document conversions, and built-in OS tools can handle image compression and format changes without uploading anything.

LPT: At a gathering, if you see someone standing alone, give them a tiny job for 30 seconds so they have a reason to exist there.

If someone is standing alone, they usually just need a simple reason to join in. I give them a tiny job that takes half a minute. It breaks the awkward moment without forcing small talk or deep conversation.

Example 1 (fits almost anywhere):

Hey, can you help me pick which one looks better, this or this?

Example 2 (sarcastic for a quick laugh):

Perfect timing. You are my co host now. Help me pick the least embarrassing snack to bring over there.

Example 3 (soft and polite):

Hey, no pressure, can you help me for a second. Should I grab this drink or that one.

It is a small move, but it makes people feel included fast.

Edit: By “tiny job” I mean a tiny, low stakes excuse to talk for about 10 to 30 seconds. Not chores. Not free labor. If someone looks like they want space, I leave them alone.

Edit 2: Least embarrassing snack was a joke. Least embarrassing is stuff nobody judges, like chips, cookies, or anything with cheese. Most embarrassing is stuff like warm raisins, unsalted rice cakes, or a plain granola bar.

Edit 3: Quick examples you can use:

Introvert friendly: Hey, can you help me real quick, where is the quiet spot to sit.

Easy exit if you want to end it: Thanks, you saved me. I am going to grab water.

Neutral for almost any place: Which one should I put out first, chips or pretzels.

YSK about the "Great Library of Alexandria of the digital age": GeoCities, a vast, chaotic city of 38 million user-made websites that was almost entirely demolished by Yahoo in 2009

GeoCities was one of the first and largest social networks, a sprawling digital metropolis where users were given a small plot of "land" in themed "neighborhoods" (like "Area51" for sci-fi or "Hollywood" for movies) to build their own home pages. From 1994 to 2009, millions of people poured their hearts, hobbies, and personal histories into these pages, creating a vibrant, bizarre, and deeply human tapestry of the early internet. It was a repository of countless "firsts": first personal websites, first online communities, first digital expressions of identity for an entire generation.

Why YSK: Because in October 2009, Yahoo, its owner, flipped a switch and deleted almost all of it. An estimated 7 terabytes of unique, user-generated history—the digital equivalent of millions of personal diaries, photo albums, and manifestos—was wiped out in an instant. While a small fraction was saved by rogue archivists (the "Archive Team"), the vast majority was lost forever. It was a cultural extinction event. Understanding this loss is crucial because it's a stark reminder that our digital heritage is incredibly fragile, often held captive by corporate decisions. The photos, blogs, and profiles you create today exist on servers that can be shut down tomorrow, and the "city" you live in could become a ghost town overnight.

YSK about "Inattentional Blindness": the neurological phenomenon that proves your brain isn't showing you the full picture of reality, but actively hiding most of it from you

Inattentional Blindness is the well-documented failure to notice a fully visible, but unexpected, object because your attention was engaged on another task. The most famous experiment is the "Invisible Gorilla," where subjects are asked to count basketball passes and a staggering number of them completely fail to see a person in a gorilla suit walking through the scene. Your brain isn't a camera recording everything; it's a ruthless bouncer at the door of your perception, deciding what gets in based on a very strict guest list (what you're currently focused on). Everything else, no matter how obvious, is left outside in the cold.

Why YSK: Because this isn't just a fun party trick; it's a fundamental truth about your existence. It means that every moment of your life, you are functionally blind to a vast majority of the world around you. It explains why people miss critical information in high-stakes situations, or why eyewitness testimonies can be so unreliable. More profoundly, it's a humbling reminder that your perceived reality is not objective truth, but a heavily filtered, personalized highlight reel. The world is infinitely richer and stranger than what your brain allows you to see, and countless things are hiding from you in plain sight, waiting for you to finally look for them.

LPT: If you struggle to fall asleep, try narrating your day in third person inside your head like you're writing a novel. It shuts your brain up faster than anything else.

I stumbled on this completely by accident a few months ago. I was lying there at like 1am, thoughts jumping from a work email I forgot to send to some random argument I had in 2017, and I just started internally going "she turned off the lamp and stared at the ceiling, tired but unable to quiet her mind." Within maybe ten minutes I was out. I've tried it every night since and it works maybe 8 out of 10 times for me, which is way better than anything else I've tested. The theory I have is that it forces your brain to slow down and process things linearly instead of jumping around. You can't really narrate fast — you naturally use calm, descriptive language, and somewhere in the middle of describing how your character "pulled the blanket up and listened to the rain outside," your brain just kind of... accepts it's time to stop. It also helps if you add boring sensory details like the temperature of the room or how the pillow feels. The more mundane the better. My bf thought I was insane when I told him but he tried it after a rough week and texted me "ok thats actually wierd it worked" so now we both do it. Takes maybe 2 or 3 nights to get the hang of the format but after that it becomes weirdly automatic.

YSK about the "Frequency Illusion" (or Baader-Meinhof phenomenon): the reason why once you learn about something new, you suddenly start seeing it everywhere.

The Frequency Illusion is the cognitive bias that occurs after you first learn about a new concept, word, or idea, and then feel like you're suddenly encountering it everywhere. Think about it: you buy a new blue car, and suddenly you see blue cars all over the road. You learn a new word, and you hear it in three different conversations the next day. The world hasn't changed; your brain has. It's a two-part process: first, your selective attention is heightened for that new thing, and second, your confirmation bias kicks in, reassuring you that each new sighting is proof of its sudden ubiquity.

Why YSK: Because understanding this illusion helps you recognize it as a quirk of your perception, not a meaningful pattern or a sign from the universe. It can prevent you from drawing false conclusions, like thinking a rare problem is actually common just because you recently learned about it. It's a powerful reminder that your brain is not a passive recorder of reality, but an active filter, constantly highlighting what it considers relevant and ignoring the rest. This awareness allows you to question your own perceptions and seek more objective data before deciding something is a genuine trend.

YSK that at-home IPL devices require long-term consistency before you notice results

A lot of people try at-home IPL (intense pulsed light) devices expecting quick results, but these devices are designed to work gradually over multiple sessions rather than immediately.

Why YSK:

Because many people stop using them too early and assume they don’t work. Most at-home IPL devices are meant to be used on a schedule over several weeks or months before any noticeable reduction in hair growth happens.

For example, I started using an at-home device (the Wavytalk IPL Hair Removal Device) and realized the instructions emphasize consistency more than anything else. Missing sessions or using it irregularly can make it seem like nothing is happening.

Understanding that these devices rely on repeated use helps set more realistic expectations and prevents people from giving up too early.
