I need a change....

and I found one...it's big. But I figure if I give up NERO and Movies and eating out and everything I can quit, and go back to school. I can have a business/marketing degree from franklin in 4 quarters/ semesters. It's expensive but that's what loans are for. I've paid my other ones off. I figure if I can make 5-700 a month then my expensise are paid for, and books and things and well damn it I'm feeling uber unqualified for the job market right now. Anyone have any opinions? Wanna talk me out of this insanity? It terrifies me....but maybe it's what i should do.
