My two cents:
My high school guidance counselor gave me this advice: Treat college like a job.
Learn to manage your time; if you can't, think of this: Mon-Thurs, work. Friday (nite) and Saturday is for play. Sunday is for church and getting ready for the next week.
One thing that I didnt see mentioned is HEALTH. I was grateful for Student Health, b/c I got mono my first semester at college. After I got better, I took Vitamin C to keep my immune system up, on the advice of my PA (Physician's Assistant). Be sure to take care of yourself, meaning drink a lot of water, eat a salad every now and then, all that good stuff. BELIEVE ME, it helped a LOT when I got better.
Lastly, Have FUN!!! Hopefully, you will meet friends for life (or at least for the time youre at school).
GOOD LUCK!!
ps.. dont forget to pray. That got me thru a LOT of mess at UNC.
