1.) Try to remember when you first experienced stagefright. Somewhere in your past there was one time that set the fear and anxiety into motion. It could have been a simple teasing from a family member when you made a mistake. If you are able to pinpoint the incident, it will help you to get past your stagefright. 2.) Practice a technique called Future Shaping. Close your eyes and remember a time when you felt the most intense stagefright experience ever. See it, feel it, or imagine it in your mind. Next, imagine yourself feeling the way you WANT to feel in that situation. Imagine you're replacing one feeling for another. Practice this technique often, and you'll notice a big difference the next time you get in front of an audience.
3.) Here's a strategy that uses a little hypnosis. When you begin to feel stagefright coming on, take a minute and close your eyes. Breath deeply and slowly two or three times. Calm yourself down, then snap your fingers together when you feel better. Tell yourself that, if you should feel stagefright coming on again, you will simply release it by snapping your fingers. Practice this technique from time to time for best results.
