This should be every kid's college guide:
Top 20.
Learn to network and make social connections, learn advertising and promotional skills, learn diplomacy, perhaps learn the legal system. Classes... yeah, go and make good grades. That piece of paper opens some doors, but what you learn in class is just the fundamental stepping stones of your field. You do the real learning once you are out of college. And you better have those social/schmoozing/BSing skills honed to a razor edge to really make a difference.
Oh yeah... intern in your field during your school years if possible. That will also give you a nose ahead when it comes time to spread your wings and attack.
