me too the only ones that have stuck with me is martial arts the ukulele and japanese ive currently stopped the ukulele and martial arts because ive gotten to the point where im happy but it took me blood sweat and tears but ive gone through learning gaelic australian sign language morse code learning ice skating photography when i had access to a school owned camera lol cooking fitness sewing knitting soccer song writing just to name a few some i did for a couple years most i did for a couple days it is just so frustrating seeing what i could become trying ridiculously hard for a little while getting burnt out and upset that i wont become as skilled as i want to and essentially rage quitting i have gotten better since i got my black belt but its annoying that most other activities dont have some kind of rankbelt system where i can physically see my progress as im doing it
