This may be a little late, but the biggest thing I can impress upon anyone that is going to college is to meet as many new people as possible. Just about every freshman at every college is looking to meet new people. Some you will continue to hang out with, some you won't, but at least you'll be finding people.

Personally, I'm a really shy guy, I don't like to just go and introduce myself to people for no reason, and a bunch of people (7) from my high school came to the same university as me (Rensselaer Polytechnic Institute), and we were sort of a little clique, and I have very few additional friends up here, and that sucks!

So put on a big cheesy smile, and shake some hands...
