Speaking with stage fright is like driving with the emergency brake partially on. Your whole body trembles, your mouth gets hot and dry, you can smell the smoke rising from your armpits, and you can’t get to where you want to go—which is OFF THE FREAKING STAGE!
The only way to release the brake, according to research, is to rehearse under performance-like pressure. In other words, get acclimated to the pressure of the stage. Slowly your tension will release, and that nasty little voice inside your head will stop interrupting your concentration.
You’ll relax, become more like your best self, and speed your way up the learning curve to stardom.
