I stopped out for a few years halfway through because of a lack of clarity, and returned at 24. I was so much more focused when I went back, and I think I got a lot more out of it. I wasn't into the social scene as much, tho, which can be a drawback, but that might be why I learned more. 14 years later, I'm ready to go back for second degree in an entirely different field. College is what you make of it.
