FEAR OF EMBARRASSMENT
Here is a great exercise that is an antidote for actors who are very self conscious and are afraid of risking any behaviour that makes them feel unsafe.
This exercise is done by an actor onstage in front of the class or a scene partner. You simply step outside your comfort zone. Start by playing with your facial muscles, grimacing and make funny faces, at the same time make silly, bold sounds and encourage your body to find silly, comic and distorted positions. Speak to your audience or to imaginary people in a high-pitched and shrill voice. You can stand,sit, lay flat on the floor and make various animal sounds, clucking like a chicken, crawing like a crow or some other kind of bird. If you take many chances and really courageously stretch your behaviour, the rewards will be inspiring.
Remember take risks and be impulsive.
