I'd like to start by sharing my story with you. I'm a person who is particularly prone to internal friction and always falls into self-doubt. When I first entered university, I felt very anxious every day, and I felt that I could not adapt to the way the teacher taught and the rhythm of university life. I was afraid that the teacher would ask me to answer the question, and I was afraid that I would be embarrassed to answer the wrong question. However, I later realized that I should not think about when it would rain on a sunny day, but should break the rules and learn to love myself. Now I have learned to self-regulate, I feel less anxious, I can boldly try things that interest me, and I am not so afraid of embarrassment.
