Hi Hacker News, I'm going to college* in two weeks. I've read <http://paulgraham.com/college.html> and right now my two main goals are: get really good at hacking, and do well enough academically that grad school is an option.
What's your advice for college freshmen, HN? "What do you wish you'd known?" I'm particularly interested in surprising, non-obvious things that I am unlikely to hear from others or think of myself.
