I'm afraid people will laugh at me. How can I overcome it?

On the one hand, strive to improve yourself and improve what you think is lacking, such as personality, knowledge and ability to do things. Of course, you can't do this at once, you can do it step by step. In addition, we need to constantly improve our psychological quality, so as to face ridicule or embarrassment calmly. If you are strong, you are certainly not afraid of being laughed at.
