Son, character is a natural thing. Sometimes you are introverted and feel inferior. Maybe these factors are inherent in you. What's the use of blaming yourself?
Besides, if you act like a madman in front of acquaintances and strangers, won't you really become a madman?
So I think you are normal. I was the same when I was young. When I feel introverted and inferior, I will be very entangled. It was during that time that my heart was unusually calm and I could think about many problems. The philosophy of life I thought was the wealth of my life.
So at any time, celebrities like Degang Guo and Ou Di are actually very introverted in private, because their introversion is a saving force.
And their extroversion on the stage is to accumulate thick hair and thin hair. Grow up slowly, and you will feel that all the previous problems have been solved. Don't worry, it's okay.
