Don't forget your toothbrush!

When you travel is the perfect time to replace old items that are probably due for replacing anyway. Instead of waiting till travel day to pack your toothbrush and deodorant, and risking forgetting them, pack them when you pack your other things; then, open a new toothbrush and deodorant for at home. That way, if you use up the deodorant you can toss it, and you don't have to worry about leaving those items behind. (And when was the last time you remembered to replace that old toothbrush, anyway? Every six months, as recommended?)
