Long-time computer geek, have made a living at various times through computer support, running a non-profit, translating technical documents from Japanese to English, starting an English school in Japan, technical instruction, newspaper reporting, and selling various things. I find programming intensely interesting. I don't do it for a living, and I wonder if I would enjoy it so much if I did. The same goes for mathematics. I'm still wondering what I'll do when I grow up.
