It is if only so you are exposed to different people and points of view. There is a lot from college that is learned while not in class. I think that is an incredibly valuable part of the college experience. The tools you learn socially are in some way more important for your career than what you study. I remember in biz school how everyone joked about the BS in org. behavior classes. Looking back, the stuff discussed in those classes had a lot of value to understanding how companies large and small work. Understanding that helps you climb the ladder faster.
