The amount of sleep you get says a lot about you. Despite having just eight weeks of college experience, I'm starting to figure some things out. My findings:

10-12 hours per night:

People in this category either don't really go to class, don't really take hard classes, or are absolute geniuses. They can be spotted on campus rather easily: they don't have bloodshot eyes and aren't falling asleep in class (or aren't in class).

8-10 hours per night:

This category seems like the unattainable sweet spot. I know a couple of people who managed to achieve this, and they seem freaking happy. You can take hard classes, get your work done, manage your time, and get sleep. You can really only be in this category if you don't procrastinate compulsively. How to spot on campus: the most smiley group by far.

6-8 hours per night:

These are the grinders. People here are taking hard classes and doing absurd amounts of homework. That said, they get it done (sometimes against all odds). Being able to consistently run on 6-8 hours seems brutal to me, but for these guys it's the price that comes with a rigorous course load. How to spot on campus: in the common rooms doing work at 3 AM.

Less than 6 hours per night:

Either your body just doesn't need sleep (best-case scenario) or you're doing something wrong. Everyone has a night every couple weeks where they have to stay up (a paper due and a 7 AM practice leads to a late night and an early morning), but doing this night after night after night is not sustainable. I know one person in this category who, fortunately, just doesn't seem to need much sleep. How to spot on campus: in the common room at 5-6 AM (may or may not be doing work).

In short, we should all try to get more sleep (unless you fall into the 10-12 category, in which case I'm not sure what to tell you).
