Sounds like a case of burnout to me. I think a lot of people would envy your position, especially given today's economic climate. Without knowing anything of your situation, except that you don't want to work on computers any longer, I'd suggest taking a step back and really analyze your situation. Have a serious conversation about your immediate future with someone that you respect (parent, mentor, older friends/siblings, fellow hackers) and see what they'd say about your life, in general. Also, get out and socialize more. You obviously have a knack for putting together successful projects, so use those skills to help other people out. You will feel better about lending your skills and time to someone less fortunate.

Also, read some books? The 4 hour work week comes immediately to mind. You haven't defined success for YOUR life yet, it seems to me.
