According to masterofmusings the description is rather accurate. I don't like the age though. I did better a couple of years ago when I did this one. Anyway, here you go.

You Act Like You Are 17 Years Old

You are a teenager at heart. You don't quite feel like a grown up yet, but you don't feel like a kid. You question authority and are still trying to find your place in this world. You're quite rebellious, and you don't like being told what to do. You like to do things your way. You have your own unique style, taste in music, and outlook on life.
