Enjoy every last minute. You'll miss these days after a few months in the "real world." I know I miss those carefree days spent with my sisters in the house just goofing off. I wish I had enjoyed it more instead of trying so desperately to get through with school and taking everything so seriously.
You know what I would do? Keep a journal of your last semester in college. Then you'll be able to go back and re-live it.
