Think about it this way. What do you REALLY want to do with your life? Do you want to sell shoes, or do you want to educate people? Who is deciding your fate? You, or some asshat? If you're gong to get fired over it, tear the place apart the day before. You're not out anything except one refference...
We are all slaves to the almighty dollar, but we can make dreams a reality if we really want to. Some not as easily as others, but it can be done. You may have to take out a student loan and see if you are eligble for a cost of living loan. Yeah, it sucks, but you are pursuing what you want to do with your life.
