You've got to make sacrifices. As difficult as it may seem. Like for instance, when its a long weekend and you're tempted to go out and party with the rest of the gang - even though thats what you've been doing for the better half of it - sometimes you have to take a step back and say "that was great y'know, but now I have to see to other things... priorities".
It's so easy to get caught up in the good stuff and to want the good stuff all the time. But sometimes, we have to go through the bad stuff, to get to the good stuff. Sometimes the only road to the good stuff is through the backroad of the bad stuff.
And people approach the bad stuff less enthusiastically. Why would you want to jump up and down at the prospect of staring at a text book for the next two weeks? But good food, great friends and seemingly endless laughter... now thats worth a round of applause.
But. Sometimes. Well, most of the time; there can't be good stuff, without the bad stuff.
