People wondering why you didn't just power through your doubts may be forgetting what the world was like not too long ago. 'Nerds' weren't cool. If you chose to be a nerd it meant _offering_ yourself up as the _loser_ in every sitcom, movie, or book. Playing video games was something you were supposed to grow out of. No one was throwing 80k at a graduate just because they could pronounce 'WWW'. Perhaps most importantly, _every_ school was pushing the race to no where. If you were thinking about a 'trade' it meant you had given up and would crack out fixing sinks for the rest of your life. At _best_ computers were taught as something you'd use at other careers. Not a career itself, really.
