I wanted to add a couple of things to Guy’s list of things learn this school year.

Don’t learn facts, learn how to deal with different situations. Take an acting class and learn how to speak in front hundreds of people. Take a full course load and a part-time job to learn how to budget your time. Volunteer for a really big project that is going to change the world and hone a pragmatic idealism. Take lots of electives and figure out what gets you excited.

Meet lots of people. School is probably the best place to meet people who are smarter, and more interesting than yourself. These people will eventually be your best business contacts.

Make a few close friends. School is where you have time to make profoundly close friendships that can last the rest of your life.

Make a bunch of mistakes. School is where you can really screw up with relatively little consequence (or at least it used to be).
