I'm AuDHD, so I have a set of hobbies I rotate through to keep from burning out. Lockpicking is my most recent.

I started this summer and it's a puzzle and a fidget toy rolled into one. It's helped with dexterity and fine motor control, too. I'm not fantastic at it, but it holds my interest and it's fun exploring new locks and techniques.

The best hobby is something interesting and fun for you. You don't have to be immediately good at it, you just have to get some dopamine from it. Every brain is different, and there's no standard autism hobby. Just think about what you'd enjoy learning and get after it.
