Charactor Developement: Myself?

So I was working on my book I'm writing, doing some charactor developement, and I thought I should do that for myself.

Fifteen years old. Blond hair, blues eyes. Some people think she's funny. Has probablems with comparing herself with her older sister. She resents that B she got on her report card last semester. Likes to think that she is a good singer, in truth she is average. Likes to draw. Puts to much salt on her food. Tall, and skinny. Can eat what ever and stay the same size. Likes to show off her bicep muscles, and doesn't know why that annoys people. Doesn't know how to comfort people in moments of distress. One of her eyebrows has a calic, that makes it's hair stick up. She doesn't like the bags under her eyes. She is suprisingly shallow about one thing, height. She will never date someone shorter then her. She turns into a moody-monster when she is hungry. She doesn't know what she wants to be when you grows up, but she knows that she wants to be a mother and wife. She has planned out all of her children's names, and is shockingly determined to have an even number of two boys and two girls. She is confused and disturbed when other girls go as far as to desire a certain order to their children. Example: people saying that they want a boy first then a girl, then a girl, then a very. That disturbs her. She likes to post on a blog that has one follower, and no readers but herself. She hates having her nails painted. She has lived a suprisingly sheltered life.
