Agreed. Looking back, my only regret is not taking more advantage of the resources I had at my disposal. Here are a few things I'd do if I were to go back...
Hopefully you're going to a school with great professors, because, in my mind, that's mostly what you pay for. I'd take full advantage of the knowledge they have. Maybe even try to develop a kind of mentor relationship that could continue outside of school and beyond.
I'd also try and get a firm grasp on what I want to do with my education. The more focused you can be in your studies, the better you can utilize your resources. There's nothing worse than leaving school and realizing that there was someone who could have been an amazing resource for you, but you didn't realize it at the time.
Third, I'd remind myself to have a good time. There truly is no experience quite like going to college. It's true that learning should be the #1 priority, but I've seen so many people breeze through college with their head stuck in a book, and I happen to think that's a shame. You'll never have another opportunity to be surrounded by such a diverse group of people doing really interesting stuff. Take advantage while you can.
Take advantage of what you've paid for, but be aware that what you have paid for is far more than just access to educators and educational resources.
Make connections with as many people as you can: fellow students, grad students, professors, everyone. That guy who sits next to you in class might turn out to be in a position to help you out in 5 years (and you might be in a position to help him).
Take advantage of extra curricula activities, clubs, interest groups, etc. Is there something you're kind of maybe interested in? It's going to be much easier to find a group of like minded people at college than it is in the "real world".
It's my experience that almost everyone takes too much advantage of the social life and not enough of the academic life. In no way does 20-30 hours of school work a week crowd out the rich variety of social interactions a campus offers.
Just don't spend it all on the internet, is what I'm saying.
While college is primarily an opportunity to prepare for a profession, it is a great opportunity to build a social life as well that would carry beyond just college years. Colleges offer beginner's wellness courses for various hobbies or sports. Take them to try activities and find what you like. It will be much easier to make and retain friends when you have a common interest that involves doing something together beyond just watching TV or movies or eating. The wellness courses at universities are also more comfortable as everyone is of the same background.
A lot of beginner's courses outside of universities are targeted to kids (AKA not you). While you could take wellness courses at universities while working, it's not easy to schedule (unlike night courses on professional topics).
