How to let oneself become not stage fright?

The main reason for stage fright is that you are not confident in yourself. You should see your talents as much as possible, and don't always compare your disadvantages with the advantages of others.

Keep a normal mind and tell yourself to calm down and relax. Being nervous can only be a bad thing. Even if you fail, treat it as an exercise to enrich your ability. There will be better opportunities in the future.

Establish psychological advantages, put yourself in an equal position with the other party (such as the audience or interviewer), and don't feel inferior. You can also imagine the other person as a mature person. While waiting for the first interview, I hinted that the other person was more nervous than me, and the whole process was very easy.
