I'd like to be a Graphic Designer....suggestions?

Hey everyone! This is a personal plea:

I’m hoping to be a graphic designer sometime after I graduate from college (this semester) and I have pretty much no idea what I’m doing. I’m a studio art and chem major (no graphic design major at my school), and I’m in the beginnings, but here’s what I’m wondering…

How did all of you designers start out? Did you all have a degree in Graphic Design, or did you get more from experience? If so, how on earth do you find entry-level jobs? It seems like all graphic design positions require at least 4 years of experience…
