When I was younger I used to be interest in computers - now not so much, but it's my most marketable skill, so I've been making money doing web development. Solving problems is rewarding, but the problems are meaningless. I'm trying to figure out what I enjoy and what provides real value.
I've had a diverse range of hobbies. I knit and craft in general. Do electronics count as crafts? I made guitar effects pedals for two friends last Christmas. I used to make fireworks, but I don't have any chemicals now. I've tried to paint, and I'd like to keep trying. I drink tea, and I love when my friends want tea because I get to do an informal gongfu tea ceremony. I've been trying to play guitar and drums for a little while - not long enough to be any good though.
