Since you are in college, I would try to find a job at the school that involves sitting behind a desk. Do you have an information center or a library checkout desk or anything like that? I had several friends who worked at jobs like that in school. When they weren't on facebook or aim, they did very little actual work for their job and studied.
Pretty sure that's what the job expect you to do, so they don't really come down on you too much as long as you can multitask.
Doing the makeup thing is pretty good to if you think you can rock it. I'm trying to get my skills up so that can be my hustle in med school too!
