Figure out what's working and what's not in your locker space. Take everything out of your locker and put it into three piles: Throw Away, Keep, and Take Home.
Do a little locker decor shopping over the holiday break. Invest in some shelves and hang up a dry erase board that you can for reminders and to-do lists.
Pack an emergency bag with stuff like mints, hair ties, deodorant, perfume, pads/tampons, hand lotion, hand sanitizer, and lip balm and hang it on an adhesive hook on your door.
