I seem to do everything in cycles of 6-9 months for some reason

I can't keep an interest for too long! Is it ADHD? I was obsessed with English so I learned English. Then I became obsessed with another language and learned it. I became obsessed with drawing and painting so I spent months practicing 9 hours a day. I became obsessed with programming, so I spent months building project after project while learning it. I became obsessed with crypto and writing so I made this blog and I'd say it succeeded massively, although as with all hobbies I took it up for a few months and left the project.

So many things I do follow the same pattern. I became obsessed with learning guitar, got a guitar and then left it gathering dust. Became obsessed with learning how to sing so I took lessons and then left it as soon as the first obstacle arrived, and haven't taken it up ever since. I have so many skills, yet use so few.

I'm now becoming obsessed with drumming so I'm looking into buying a drumming e-kit. I'll probably have to resell it after a few months if I do get it. Honestly I can't take myself seriously after all this time. It's like I know anything I do I'll just fatally lose interest and let everything die and rot while my attention span obsesses over the next shiny new thing. It was LLMs at a certain point, image generation at another point.

I've kept a few hobbies since then. Mostly programming, and the games AoE2:DE, Tetris (on Jstris mostly), Chess and earning money (it's hard to not pay attention to it when it runs your life). I really wanna do something entertaining. I see people with hobbies that last decades! I wonder what they've got that I don't.

Maybe I just love learning. Maybe that's where I thrive. Maybe once I've learned enough that the rest is just smooth sailing it loses my focus. Maybe that's why I still go back to challenging games where I can always reach a better score, learn to be more efficient and competitive. Maybe that's the key in the end.

Competitive programming then? Could be a solution to my woes of rusting coding abilities during employment downtimes.?
