Guys, what advice do you have for a girl that is intelligent but doesn't turn any heads?

Why does beauty seem to be the defining factor in what attracts guys to women. I'm a 23 year old female - I believe that I'm friendly and easy to get along with, but I've never had a date before. I'm in graduate school and I used to think it was just my lack of time that was preventing me from finding anyone, but there amongst a group of very busy, educated females, the more attractive one always gets the dates. Guys, what advice do you have for a girl that does not necessarily turn any heads from guys? I'm striving to get into medical school, so I'm quite busy as it is, but sometimes I get a bit down about my situation.Guys, what advice do you have for a girl that is intelligent but doesn't turn any heads?
