For me it’s time signatures in music. I grew up playing instruments, played in several orchestras, etc. But no matter how many times someone tries to explain time signatures to me, it makes no sense. I don’t understand why people place such importance on it. To me, notes have a pitch and a duration, maybe some dynamics. That’s it. I don’t understand why people try to needlessly complicate it. It doesn’t give you anything.
My wife will hear a song and go “Oh neat, it’s in 5/8.” And I’m like “How tf do you know that, and why does it matter?”
Choreography. Not just dance moves, but any physical activity where I watch someone do a thing and have to repeat it using my own body. Had a hell of a time learning to tie a necktie.
It’s a skill! If you’re interested maybe join a dance class, boxing/MMA class, pottery class, or do some improv!
