The first thing that should happen when you go out to the audience is not just a smile like it's your duty, you should not just look the people in the eye, you should have fun. The pleasure of what you do, the fact that the spectators are contemplating you, the fact that you receive feedback. You are given applause – make a pause, look at the audience. If you are not applauded, make a pause, applaud yourself, let the audience applaud you too.
