Stop trying to impress others. No one really cares. You have to impress yourself. Do something that would shock yourself everyday and keep doing those things.
Don't cry over that guy and don't chase after him. Chasing is for girls who don't think that they're good enough.
You are fabulous and have such a special gift in you. Never, ever give up on your dreams and the more people knock you down, the more you gotta push harder because so many wonderful things lie ahead.
Take some Spanish in high school, not German. Although Deutch is a kick-ass language, Spanish will benefit you in every field - especially the restaurant industry.
Not everyone is going to love you but the people that do are what make life worth living.
Don't ever think you're not good enough. Confidence is the best looking thing about you.
Don't give into peer pressure. If you feel like friends are pressuring you to do something you don't feel comfortable with, then they're not good friends. You'll make better ones along the way anyway.
Keep having dance parties until there is no other option but being in a wheelchair.
Don't spend so much money on cheap shoes. They end up hurting your feet in the long run.
Don't change your personality so you can hang out with people just to "fit in". If they don't like the fun, crazy, honest person that you are then they can piss off!
Don't try to be the best. Just like how there is always someone taller, prettier, and smarter than you - there is also someone shorter, uglier, and dumber than you.
You're friends will change and that's ok because change isn't as scary as you think it is. Sometimes they will change for the better, sometimes the worst. But everyone's going to have to find their own way and you can't change that. Just remember that family is more important than you will ever realize.
Keep Disney music on your iPod always. It will faire well in many a road trip or bad day at work.
