Big enough that you will find your place in it. But only if you look. Enjoy your time, don't waste it away complaining or being afraid. You will never have a time in your life when you've had it so good or so easy. Seriously. Let yourself enjoy it, but don't be stupid and get too caught up in BS or let yourself flunk out. If your accepted into this school you are already smart enough, its just a test of maturity, but don't take it too seriously or you will miss out on all the fun. Go to one of each type of sports event at least once. Play frisbee or sunbathe on the quad at least once. Slip on the ice on your way to class at least once. Use a fake ID at least once. Got it? Good. Don't waste it, its over before you know.
