As some one who worked all through college, I would do it if you can juggle school work and job, with out letting one affect the other. I personally needed to work to pay for my own stuff, like car, insurance, and college fees themselves.
If working becomes a problem for you to maintain the kind of GPA you want to have, then maybe don't work. If nothing else, it will give you good life experience. Working for someone or a company will give you an idea into what the "real world" is really like, for when you get your degree..an edge you will have over you fellow students who didn't work through school.
Plus, if you listen to Omar, its takes money to bang chicks...alcohol aint free
