Classes are over. It's cold outside. No one blames you for wanting to find your footie pajamas and hibernate. Winter break is the time to decompress and enjoy the holidays. Give yourself some leisure time to rest, read, and recuperate. Reflect on all that you've accomplished and what's coming in the new year.
If you haven't finished your college admissions paperwork, use the time you have away from school to concentrate on putting together an excellent application. Draft and polish your essays and ask for help proofreading; others will catch mistakes or confusing language that you may miss.
Don't take on the world during your vacation. Give yourself a break so you can start the spring semester rested and ready.
