Teenager in theHouse

While I might be in a bit of a rant, I am very tired of my soon to be 13 year old. She is a great little person, smart, pretty and kind to people (who don't live with her) and generally has her head about her. But i am so tired of her acting like she is entitled to all the riches in the world and we are only there to provide what she needs. We try everything and yet, still she approaches us with disdain. It is driving me crazy. I want to have the courage to just take everything away and make her earn back every privilege. Somehow, I think the message will be lost. Maybe the deal is not letting her have any more privileges. How do we get her to earn? How do we get her to buy into accomplishing her own goals? Am I expecting too much of her? Do I just let her be who she is and let her make her mistakes and pay for them. She doesn't seem to want or heed our direction. I wonder if I just stop even trying.
