People who say the awesome careers just happened to them are lying. Nobody takes one class for fun and then becomes rich and famous. There's a lot of hard work, striving, rejection, and stepping on people that goes into it too.

Just, y'know, if it makes you feel any better. Can you try working one job to pay the bills and then volunteering or something else at a place you'd enjoy? Or what about temping? That pays pretty well, and you'd get to work in an office.
