What are some things that are worthwhile to memorize?

Honestly, I reckon the most useful things to keep in your head aren't those fancy academic theories but the basic stuff that gets you through the day without a phone. Like, knowing how to do quick mental math is a lifesaver. If you're buying materials, you gotta be able to calculate things like 15 * 12 or figure out a percentage on the fly without fumbling for a calculator. It keeps you from getting ripped off and makes you look sharp when you're dealing with numbers in real time.

Aside from numbers, memorizing emergency info is just common sense. Knowing your own important numbers, addresses, and maybe even a few basic first aid steps will get you out of a jam way faster than scrolling through an app. Also, try to memorize a few good jokes or interesting facts about stuff you actually enjoy. It makes social situations way less awkward when you're just standing around waiting for something to happen and you've got something decent to talk about.

Lastly, don't underestimate the power of memorizing directions or how things are built. I’ve spent years working with my hands, and realizing how a structure goes together in my head has saved me so much time. If you can visualize how things fit or how to get from point a to point b without a gps, you start seeing the world a bit differently. It’s not about being a human encyclopedia, just about having a few handy tools tucked away in your brain for whenever you need them.
