On my experience in the college, I can give some advices: - Try to sleep a lot. When you can sleep, SLEEP! - Try to do your works with time. Sometimes it's imposible, the works accumulates and you colapse, so try that doesn't happen. - Choose something what you REALLY like or something on what you are REALLY good, not everyone is good in what they want, but the frustration is a fact. - Don't mix your personal life with your studies. Sometimes the thind doesn't going well and you can collapse.
