I would suggest a part-time job as well. That's my situation right now. I'm a soon-to-be-grad, and I'm doing part-time school, part-time work at a software company. One or two days a week there (depending on my work load at school) pays my living expenses, tuition and loan repayments.

If I weren't in school, and didn't have student debt, I could live quite well on the same amount of income, yet bootstrap a startup at the same time.

Mind you, this requires a well-paying and flexible part-time job, but it's definitely possible.
