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.
People who have no problem getting up in front of a crowd seem to have success fall into their laps. Always being ready to speak will make others see you as a leader. You'll get more prospects, move up at work, and gain the admiration of others.
