Fear is not your enemy. Fear triggers physical changes that prepares the body to fight or flee a dangerous situation. These responses include an increase in the heart rate, perspiration and tightening of muscles. Do not fear, fear can be used to your advantage. The key is not to push fear away but to recognize it and deal with it.
Fear feeds on the unknown.
Once you looked under the bed a few times and learned that there really wasn't anything under there but a few dust bunnies, your fear went away. You confronted your fear and found that your fear was not justified. Soon you will learn that competition does justify an all out fight or flight response. First you must rationalize. Your life does not lie in the hands of those judges.
