I think I may have hit on something important: when I study in the library, there's no way for me to take a short break (like five or ten minutes), because every time I take a break I have to pack up all my stuff and put it in my locker and then go back and take it out later. If I studied more at home, I would be able to go for an hour and then stop for five minutes and then go for another hour and stop for ten minutes, and so on. When I study at the library, I'm basically forcing myself to either rally through a solid three or four hours of studying or else punt after two hours (like I feel like doing now) and blow off the rest of the time until class. Maybe I need to study more at home. Unfortunately, I can't possibly park unless I get to school by around 7:30 or 7:45, and then I don't have class until 11 most days. So what am I going to do until then if not study? Maybe I could go to the gym in the morning instead. But I think I'm safe in saying that most normal people don't try to study for four hours straight every day. That's just lethal. I need a different way of doing things.
