Develop a solid layer of fat to protect yourself from the cold: odds are you've already gotten a head-start on this one thanks to your campus dining center and drunken late-night pizza binges.  While your unsightly rolls of fat may lead you to believe that you are less than attractive to members of the opposite sex, which you definitely are, you can hide your disgusting and well-insulated body in layers of sweat pants and hoodies.

Find a ride home for Thanksgiving/Christmas: now is the time to reconnect with your annoying high school friend with a car who goes to your school.  Sure, the kid was annoying as hell and always wanted to tag along with you during Welcome Week, but his beat up Saturn is better than sitting next to a possible prison-escapee on a Greyhound.

Re-establish contact with your high school ex-girlfriend: now is the time for several well-placed facebook messages about wanting to catch up (i.e. hook-up) over break.  The endless parade of drunk co-eds comes to a grinding halt the second you step foot into your childhood room, so make sure that you mend the fences that resulted from breaking up with her a week before you both left for school.
