At Emory from students I talked to, it seems like many have part time jobs that allow them to explore interests, meet people, gain experience. I'd think you'd really miss out by not being able to participate flexibly in some of those things. I am not sure if it's different at other schools.
That's what I worry about, but I'm also semi-afraid to leave my job now that I think about it...and am feeling very proprietary about it aghh...like it's *my* job. This is what happens when it's your first full-time "adult" job. 😱 I don't want to leave the nest...
