How to change your vehicle's tire SAFELY.

Basic home maintenance or at the very least troubleshooting and diagnostics when something breaks so you can give the repair tech better info when they arrive.

Basic home cleaning. This one might sound obvious but the number of people I've worked with who've never held a mop before astounds me. Learn to do your own laundry and clean your bathroom and kitchen well and efficiently. Learn what it takes to do a quick clean and a deep clean and do them on a schedule.

Formal Logic. Please, can this be a full k-12 course like English and Math? Just learn to think, analyse, and correlate ideas in ways that are communicable. Learn what the logical fallacies are and how to avoid them. Train a functional bullshit detector. This world would be so much better off if the bulk of the population could understand what a confirmation bias was. As much as I hate to link to a Grammarly blog post, it gives good examples. Obviously all of it needs to be made age appropriate, but we never bother to actually teach people how to think, we just expect them to know and that has not been working out too well.

Sewing. I've saved a lot of shirts putting buttons back on and fixing holes. You can also do your own alterations on clothes but I'm not brave enough to try that yet.

CPR, first aid, basic self defense.

First aid.

Learn a dance or two nothing too complicated but being able to bust out a dance at a wedding really impressed everyone.

sewing with a needle and thread. nothing complicated, the bare minimum is useful in a lot of ways.

i keep a small kit in my car because my pants waistlines keep shrinking mysteriously and i'm starting to randomly lose buttons and getting blowouts in the crotch. [likely due to far-reaching, nefarious, conspiracies and not b/c of the other kit in my car that's full of snacks].

what used to be my crippling, irrational fear of inadvertently exposing myself at like a job interview or in an uber with a cute driver, is now an easy fix i can do in a minute AND it's certain to make an impression.

old winter jackets with a lot of zippered pockets are especially great practice. try unstitching and removing a few of the pockets, then add them to other jackets or whatever you can think of.
