Fork3, in college if you are not passionate about what you're studying, you're in the wrong major. At 21, you might try a hitch in the service. It will give you new perspectives on your fellow Americans, our history and make you a better citizen. If I had it to do over I would have joined the Marines. They are a lot like a fraternity after you get out. Of course you need to be in shape to join any branch now. There are many benefits such as the GI Bill and home loans but it is the experience that will mature you.
