Confidence and experience are important keys. Being prepared and knowing your stuff is ready makes a big difference. It's all in the head. Be positive and don't let anything take it from you.

Not caring just lowers your expectations. So when you do bad it doesn't bother you. Not healthy. You need to aim high and have mercy and grace for yourself. Don't beat yourself up. Do your best to stay positive. Surround yourself with positive and successful people that draw the best out of you.

Don't medicate yourself. Numbing yourself isn't healthy either. Drugs are not the answer.

We all make mistakes just like the pro's. They just make fewer mistakes.
