How can I not get stage fright?

I care too much about other people's opinions and expressions, which leads to my inattention in my language and actions.

But just look at other people's reactions.

Actually, you don't have to. They came to see your performance. There are many other performances behind, so you should have confidence. Believe that you are doing better than others. Even if in fact you are not as good as them, tell yourself that you will become stronger this time. Secondly, don't pay special attention to the audience. Look at the distance and the roof of the hall. Nobody pays attention to you there, just like performing for yourself in an empty room. Third, we should slow down.

Take a deep breath. Try to relax yourself. Let the body become soft and relaxed, or give yourself a psychological hint, think of something happy, or a ridiculous joke.

. of course

Don't concentrate too much, it will delay business.
