Do you have any advice for a first-year college student?

I’m leaving for college in 3 days (shit) and was wondering if any of you wise Flutherites could give me some helpful tips that you may have garnered from your experiences. I know basics like “Get to know your professor”... “Get involved in activities on campus”. But if you have any interesting tidbits to share that you think I might not know, I’d appreciate it.
