I will admit that, to become a supervisor at my job you have to have a college degree--not that it helps. Also, there are people at my job (nuclear power plant) who walk in the front door making triple what I make based on the department they work in. Hell, they probably make more than I make a year in bonuses alone!
I guess I cut myself out of a lot of opportunities but, at the same time, I'm doing better than I ever imagined I would.
