I'm not going to be one of those people who studies 24/7 for a year. I just can't do that, i'll lose motivation and give up. I'm not giving up Facebook, not giving up video games, not giving up my job and not giving up extra curricular activities. From what i've heard from former students it's all about balance. Obviously if you're on Facebook 24/7 or working 20+ hours a week you're probably not going to do as well, but if it's in moderation then I don't see a problem.
