Cut Your Bandaids
Everyone always forgets that we can cut bandaids to fit where the injury is! For particularly difficult spots like fingers, joints, and toes, cut the bandaid so that it's easy to wrap around your wound. You don't have to stick to the normal bandaid shape.
Polished and Organized
At some point in your life, you realize that you have tons of keys on your keychain. Where are they from? What do they go to? How did they get there? No worries, though, because there's a cheap alternative for marking your keys! Take any available nail polish you have and paint the ends of the keys. That way you have a color code for which key goes to what.
