Younger Answer: When I was younger, I wanted to be a paleontologist...digging up and studying dinosaurs. (At this point, its only a hobby.) Then I got into computers.
Right now, if I could have any particular job, I think I'd want something similar to what I do now, but I'd prefer an older crowd with more computer knowledge. These kids after school are going to cause me to pull out my hair.
I could see myself with a LAN party center, offering business-related computer services and high-speed internet gaming...for a price.
Older Answer: What I do now is to monitor an 8-computer 'technology center' at my local library, which is a whole 0.3 miles from home, so I walk to work daily.
