The qualities you should possess are self-confidence, principles and ideas. The most important thing is to have a practice and know how to do it. I suggest you read more books on emotional intelligence, with examples. If you cultivate them, you should boldly apply what you have learned to your life and do what you dare not do. At that time, you will gradually have a strong confidence in life. You should also pay more attention to the things around you and study more. In a word, learn from them what you think is good, discard what you think is bad, and then you will be handy in everything you do. I forgot the title of the book. I just read some books about biographies of heroes, such as Yi Zhongtian's Three Kingdoms, Mao Zedong's biography, Liu Bang's legend and so on.
