I'm not talking about social skills or time management. I'm talking random abilities that are interesting to have such as solving rubik's cube or rolling a coin in your knuckles. What random little things can you think of that, while having no obvious benefit, are cool to have?

I gotta work on my people things

Spending time with my people
I'm getting way too busy

I want to learn how to flick cards accurately and with power. Like in magic shows but my purpose is so I can give a bunch of very painful paper cuts to people I don’t like. Also as a game no one can beat me in.

Learn how to tie strong knots. Look up books of sailor’s knots and things, and learn how to tie loose and tight knots. Very useful skill to possess.
