What should I keep in my purse?

Okay, I'm 13. Usually, I carry around a medium/large sized Vera Bradly Bag.
This is what I keep in my purse. Too much? Anything I missed?

Cell Phone (an iPhone, so I don't carry around my iPod)
House Key
Wallet (with money, of course)
Makeup: Chapstick, lip gloss, small eyeshadow palette, mascara
Small mirror
Feminine Supplies
One pencil, two pens
School ID (in wallet)
Library Card (in wallet)
Deodorant (if going to do something physical)
Notepad
Mini hairbrush
Hand cream

No, this seems fine

Sounds good, but, I also like to keep a pair of socks in case you are going shoe shopping!

Safety pins (trust me they come in handy more than you think)
Headphones/Earbuds
Any medications you take.
Blotting papers (if your skin ever gets oily)
Mini toothbrush and toothpaste (not necessary but I'm a person who likes to brush their teeth after EVERY meal)
Credit card if you don't have one and you are responsible, once you run into an emergency you'll be thankful you have it.
