Don't fill your bag up with useless items you're never going to use. Stick stuff in there that's actually going to come in handy. That way, you'll always be prepared in any given situation. Here are a few pocketbook essentials you should keep on you at all times:
1. Hand Sanitizer
If you don't have time to wash your hands before a meal, you can at least use hand sanitizer. The miniature bottles from Bath and Body Works are easy to fit in the side pocket of your bag, so they won't take up much space.
