I was in a similar boat as you 2 years ago, and I wish I did two (seemingly contradictory) things different: 1st, go outside of your majors - take some acting classes, some poetry classes, some philosophy classes. 2nd, understand your majors - take a couple of hours to research every class your major offers, and decide which ones sound appealing early on - at Rutgers, I finished a CS BA without taking a compilers or OS course, which was, in hindsight pretty clearly, a mistake.
