LPT : Anyone else feel like they waste hours on their phone without realizing it?
I’ve been trying to fix my productivity, but I keep losing 4–5 hours a day just scrolling, especially on reels and shorts. Even when I have a to-do list ready, I somehow end up picking up my phone or laptop and falling into the same cycle.
Looking for people who have been suffering/suffered same problem, to discuss it out? What helped you guys out , any tips?

LPT: if a microphone starts feeding back, hold it closer to your mouth, not further away.
When a microphone starts feeding back, i.e. that awkward ringing sound, everyone’s instinct is to move the microphone further away bc they think they’re being too loud. In reality, the opposite is true, you are being too quiet, thus the sound person has had to turn up the volume way too much to compensate.
Move the microphone closer and speak louder, and they can turn the volume back down so that it stops ringing.

LPT: If you feel heavy or bloated after meals, try sipping a glass of lukewarm water (around 40–50 °C) about 20 minutes later, it may support digestion and ease discomfort.
Warm water is gentler on your system and can help food move more smoothly through your digestive tract. A 2023 clinical study even showed that drinking warm water after meals led to gradual weight and BMI reduction over 3 months, without side effects. It’s a simple habit followed in many cultures and may help reduce that sluggish, full feeling after eating. Just sip slowly and stay consistent.

LPT I've reached peak lazy efficiency with my morning routine and I'm proud!
So I have two old ice cream containers (because of course I kept them) that I've turned into my personal brain-saver system. One sits in the drawer empty, the other is stacked on top loaded with all my toiletries.
Every morning: grab the full box, do my thing. As I use each item, I drop it in the empty box like I'm playing the world's most boring basketball. When the top box is empty = routine complete, no thinking required.
Then I just swap them and reset for tomorrow. It's like having a save file for my bathroom routine.
My brain is now free to focus on more important things, like wondering if cereal is soup or debating whether I actually need to wash my hair today (the answer is always no because my routine starts after the shower).

YSK: uBlock Origin is vastly superior to most other ad blockers in privacy, performance, and control — and many "ad blockers" are actually scams or sell your data
Why YSK: Most people assume all ad blockers are the same. They aren’t.
Many extensions calling themselves “ad blockers” either:
Allow certain ads through a "whitelist" in exchange for money (e.g. Adblock Plus),
Track you or sell your data (some Chrome extensions do this quietly),
Use too much memory or CPU,
Or simply don’t block well (ineffective filters or slow updates).
I find many people still using adblock plus or adblock because it's the first thing they see when they search for an ad blocking extension. Always research up on extensions you decide to install blindly.
Also, it's best to use uBlock Origin in Firefox, not Chrome as uBlock was recently removed from Google chrome store for not following "Best Practices".
Firefox still supports the manifest V2 which makes extensions have a lot more power and control rather than the watered down manifest V3.

YSK how the scientists and doctors update their beliefs
Why YSK: We know that correlation is not causation, but we don't know how correlations alone can give us unexpected conclusions, simply by understanding the Bayes' Theorem. Moreover, doctors use it frequently to assess the false positives/negatives in the test results. Understanding it intuitively can prove to be a tool to further sharpen our critical thinking skills.
The video on Bayes' Theorem by 3Blue1Brown is the best starting point: https://youtu.be/HZGCoVF3YvM
To understand Bayes' Theorem, let's take a textbook example: here's a two-headed coin and a fair coin. One of the coins was tossed and it turned out to be heads. Then what is the chance that the coin is a fair coin? (Answer is 33.33%)
Here, we know how likely it is in a fair coin to have heads. Bayes Theorem answers the question, "How likely is it a coin with heads to be the fair one?"
In other words, it flips the condition and gives us a nice way to how our changing beliefs might fit into the things we already know. In this case, adding a two-headed coin instead of (probably) another fair coin made us curious to know how our conclusions might have changed.

LPT Arguments don’t ruin real friendships they reveal them
If someone shows a completely different side of themselves during a disagreement getting mean, manipulative, gaslighting or ditching you for another group they’re showing you who they really are. Real friends might argue, but they work through it and come back stronger. If they cut you off or switch sides the moment things get hard, they were never really there for you in the first place. Conflict doesn’t break true bonds it exposes fake ones.

LPT: The wedding toast
Wedding season is upon us. I have been a best man three times and have been to over a hundred weddings. How to do it:
Come up with one to three grandmother-appropriate stories about the person you are toasting. They can be funny, but must be uplifting and positive. The last story needs to be heartwarming and make your toastee seem like the greatest person who has ever lived.
Get the stories down to five minutes total. From introducing yourself to toasting, five minutes. People will talk about great wedding speeches that were longer, but every one of them would have been better if kept to five minutes. The best one I have ever seen was one minute long, and it left most people in tears and awestruck.
Now ... Where people get it wrong. You're not an exception, just trust me and follow the playbook.
- Going too long. Five minutes MAX. At six minutes you're starting to lose people, at ten they are gone forever.
- Roasting. Roasts are for the bachelor and bachelorette party. Insults of any kind are out. I have seen lifelong friendships die because of this. Don't do it. You are not an exception. It is better if your speech is forgettable rather than devastating. I got roasted at my wedding. It hurt, it wasn't funny, the guests were aghast. Many of them apologized on behalf of my best man. I let it go after a couple of weeks, but not everyone will.
- Inappropriateness. If you wouldn't say it in front of the King of England, don't say it in your speech. Do not mention exes or sex, ever.
- Talking about yourself. Leave the I's out of it. Turn every story so you are talking about the toastee. It's a great idea to seek out stories from people where you weren't even present. This speech has absolutely nothing to do with you.
- Inside jokes. Your speech is for your audience, not you. No inside jokes.
- Not introducing yourself. Forgetting to toast.
- Being drunk.
- Not practicing, and not timing your speech.
Crying is okay, but don't let it take you down into how proud you are of your friend and the woman or man they have become and all that cliche nonsense. Fight through it, it will be seen as endearing, and get back on track. Include crying in your practice runs to simulate if it happens. It helps.
Best of luck.

YSK that turning on subtitles while watching shows can boost your focus, memory, and vocabulary, even if you're fluent.
Why YSK: Reading captions while listening helps your brain build stronger connections, activating both visual and auditory pathways simultaneously. Research shows this dual engagement enhances comprehension, attention, and recall, even for native speakers watching in their own language. It’s like free mental exercise: you learn new words, catch nuances, and naturally stay more engaged.

LPT: Career change and dropping out can be wise decisions.
I'd like to share this experience of my life in case it can help anyone out there!
I'm a 25 years old female. During high school, I put in long hours of studying to be able to get to best schools and top fields! After studying 8-10 hours day for over a year, I got into medical school in one of the top universities in Iran. Unfortunately after just one semester, the educational system really disappointed me, from our evaluation system (which was brutal) to our profs' teaching style and behaviour towards students.
On top of that I was not happy with the people I've been surrounded with, I did not feel inspired! Something inside me kept telling me "You tried THAT hard to achieve this? This is far from expectations".
Long story short, I dropped out after nearly 3 semesters, took my english test in 3 months and immigrated to Canada. At the time, dropping out of medical school was considered a radical decision (I know these days it has become easier since more people are doing it).
In Canada, I got my bachelor degree (3.92 GPA) in neuroscience from university of Calgary. After working for over a year in life science sector, I decided to quit to pursue something else (which is not even science-related).
I wrote all of that to say that it's easy to say oh you've wasted your time and life by switching fields and careers (believe me I'd blamed myself as well). but now I look back and I think my strongest skill sets have come from that time where I studied those many hours! why? because it taught me self-discipline and time management!
My biggest take-home message is that if you made a wrong decision (career-wise or anything), Just ACCEPT it and try to move on and find another path! Do not get stuck and hope life resolves in itself!

YSK: You can get a free replacement for most lost or damaged charging cables directly from the manufacturer — even out of warranty
Why YSK:
A lot of big tech brands (like Anker, Logitech, or even Apple in some cases) have customer-friendly policies where they’ll replace damaged or frayed cables — sometimes even if you didn’t register the product or if it’s out of warranty. You just need to contact support with a serial number or order ID.
This applies especially if you bought from Amazon or the brand’s official site. It saves you from wasting money on new cables when your current one was technically covered all along.
