Uhm, when you graduate, you will realize that fun should be toned down. I can't sacrifice education for fun, just like I did as an undergraduate. You will then realize that your future relies on what and how you study. Also, since I experienced a rejection in one of the masters, I honestly can't fall into that trap of being a teenager anymore. I had my fun, I won't stop having fun, but it won't be an obstacle to my studies either.
