For me it's mostly that I want to keep my girlfriend happy and I try to get at least acceptable grades so I dont have to worry about getting accepted into work after my apprenticeship.
But a bit it is also the problem, that when I *could* log, other games seem more rewarding to play. It's sad to admit that, but it is like that, many times. I hope I can get back into it more soon, but with the final exam coming up in only a few months, it's getting kinda tight on schedule.
