What's the one thing that you want to achieve in life?

I've not done it yet and apparently it's never to be done, it's impossible. I'm only 11, and I've always wanted to lead a normal life, not a complicated family history like now. My dad's turning 60 this year. Mom's only 42. It's an 18 year old difference. I have 2 stepsisters and 2 normal sisters and 1 stepbrother. I have a stepmom too. She has a cold heart and a fishy face. I dislike her and obviously she hates me too. Sigh... =(
