Exactly, same here...I've never NOT held down a job since the beginning of freshman year of undergrad, and feel weird not being employed for even a few weeks...I think working gives you a (gee whiz) important work ethic that living off of loans does not...in the latter, it's no different than your rich surgeon mommy or daddy paying your way through school; only when you are a rich surgeon yourself, you have to pay it off yourself
and besides, nothing against waitresses, but even for part-time positions as a full-time student, there are plenty of other things you can do besides working in the food service area, and paid jobs in the medical sector can give you much more inroads into life as a doctor than glorified candy striping (now, working hands-on in a ER or something is a different story, but sitting reading books to old people, while a nice, caring gesture, doesn't stand out in my mind as what makes a successful physician)
