Here's some advice for college:
Go to class, take notes, study, and get good grades. If you aren't getting mostly A's, then you shouldn't be in college. Undergrad is ridiculously easy. Get A's, and you allow yourself many more opportunities in the future, like being able to get into grad school. Unless your major is engineering, science, math, and maybe some business degrees, a bachelor's degree is not worth much these days. You need a graduate degree to make decent money, and a lot of mid-20somethings find themselves unable to get into grad school because they are haunted by a low undergrad gpa from years ago.
Put school first, and partying second, and this will still leave a lot of time for partying.
