My body's trained at this point to never sleep pass 7:30. It wasn't a conscious decision. That was just when I had to get up for school, and it's stuck. This morning, for example, I had only slept for about 6 hours, but at 7:30 I was wide awake and not even remotely able to get back to sleep. Granted, there are times when the power of sleep will win, but it only happens when I stay up until like 2 AM and there's no way I'd be able to function on that amount of sleep. It's kind of nice though, because I always feel like I get more accomplished when I'm up that early. It seems like time goes by a bit slower in the mornings, and I can just relax and listen to music without feeling like I'm wasting my day.
