Try to find some good friends in CS (or whatever your major is). I made the mistake my first year of college of being far too standoffish and irritated with most of the people at my first school, and spent most of my time bored and lonely until the middle of my second semester, by which point I'd already made plans to transfer out.

I considered myself a pretty outgoing person before I left for school, but moving away from all of my high school friends had a bigger effect on me than I'd expected.
