For me? I'm a huge nerd...
I built my first computer when I was in 3rd grade. I started working with linux by 5th grade, by 6th grade I was writing code.
By 7th grade I started writing Unix tutorials for n00bs, mainly on how to get hardware drivers to work on different linux distros (it took me months to figure out linux, especially back then when it was still fresh).
By 8th grade I had not only learned how to hardware hack, software crack, and all those cool techniques (like mysql injections), but also taught myself how to wire home theater systems, car stereos/audio, etc. (got bored of all the coding).
By the time I hit highschool I was whoring myself out for 50$/hour. Business really took off when Best Buy came out with geeksquad, you have no idea how many home theatre systems and home networks I had to fix after GS effed the install up. I also built web-based programs and websites for a few people, I didn't make a whole lot, like 300 a website. It's ironic though, Best Buy wouldn't hire me, told me I was too arrogant, that's why I had to go work for myself.
However, I guess I don't look like the type, because everyone seems to think I'm technologically illiterate.
Oh yeah I smoke crack too.
