Learning to find more time?

It's one day before my first exam, and as the hours fly by, and the test approaches, faster and faster, I realize that going to school part time might be harder than I imagined. It's not that the class load is overwhelming, but the fact that I have less free time, less hours during the day with a clear mind. If it isn't homework, it's work and projects. If it isn't one of those two, than it's the condo, or relationships. It just seems like the phrase, "pick and choose your battles" is becoming my new life. And that's the problem, I don't like having to let some things go. I want to win them all, I want to be able to give my full attention and detail to everything I do. The problem, is that I just can't anymore. So tonight I will study, and tomorrow I will take my exam, so wish me good luck!
