LPT: Memorization happens by retrieving information, not reading it.
Do a quick memory retrieval every 20 minutes and you’ll get the same effect as staring at pages for 60 minutes—except you’ll likely save 45 minutes of your precious time.
Memorization happens when you retrieve information, not when you passively read.
Wanna go pro?
Build context with every piece of information. Don’t stubbornly stick to one angle.
Ask yourself: What other content fits into the same field?
Connect ideas—you’ll expand your scope of memorization even further.
Example: If you're learning equations, tackle matrices at the same time.
Don’t wait until you master one topic—link them together in the same sprint.
Still not enough?
Professor Feynman advocated for teaching others what you’ve learned.
Even talking to a camera with a prepared flipchart does the job.
Haha, you must be kidding, Mr. Feynman!
Good luck!

YSK ChatGPT now allows the creation of photorealistic fake receipts
Example: https://i.imgur.com/MJ9Qs15.png
Why YSK: You should know this in order to be careful of receipts and the such you see online, because AI image generation has greatly advanced to the point such photorealistic image generation is possible with just a text prompt.

YSK “macaroon” and “macaron” are two different things, pronounced differently
I didn’t know about macarons - delicious French cookies made with egg whites with cream in the middle - until I was an adult.
I knew about macaroons growing up - the chewy coconut cookie - but not macarons. Until recently, I was also mistakenly under the impression that these cookies were both pronounced the same way, but “macaron” has an “awn” sound, not an “ooh” sound.
Why YSK: I work at a bakery, and more than once, people have asked me for macaroons. I lead them to the coconut cookies, and they tell me that’s not what they meant, and I say, “oh, you mean the French cookie, macarons?” (Usually, I get “I guess so,” or “I don’t know, it’s chewy and small and comes in different colors” as a response.)
Knowing the difference will help avoid confusion when you are at a bakery looking for macarons. 🙃

LPT: confidence is sexy, don’t explain your boundaries
I used to feel guilty turning people down, whether it was a date, a collab, or even just ignoring weird messages. I’d write essays trying to justify why I couldn’t do something, worried they’d be mad or think I was rude.
But one day I just said: “No thanks, that’s not for me.” No explanation. Just polite and firm.
To my surprise? Nobody fought back. Most people respected it more. Some even apologized for asking.
Turns out, confidence and boundaries are hotter than over explaining. Whether you’re in content creation, dating, or just life - say less, and own your “No.”
