10. Problem: Blisters on your feet from uncomfortable shoes. Let's be honest, you've never worn sensible shoes in your life.
Solution: Well obviously you should own at least one pair of comfortable shoes that don't have a four-inch heel — like a Chelsea boot or Chuck Taylors. Or, if you're a high-heels-or-the-highway kind of girl, keep a stash of Band-Aid Activ-Flex in your clutch. They'll save your soles, because they're soft, flexible, and provide a cushion that will prevent and protect your feet from painful blisters.
