Improve self-efficacy; Self-efficacy is an individual's belief in whether he has the ability to complete a certain job or behavior, which affects and determines the individual's behavior choice and the degree of persistence and effort in that behavior. The stronger a person's sense of self-efficacy, the higher the goal he chooses, and the stronger his perseverance and persistence in achieving it. The improvement of self-efficacy is the continuous driving force for the development of individual leadership. In the cultivation of children's leadership, to improve children's sense of self-efficacy, we must first let children get a successful experience and let them experience success in overcoming difficulties and completing tasks. Many successful experiences will improve children's self-efficacy, while many failures will reduce children's self-efficacy. Therefore, when children face complex tasks, teachers should guide them to learn how to break a big task into small tasks, so as to experience the effectiveness of their efforts and improve their sense of self-efficacy. Secondly, we should encourage, explain and guide children to feel the value and strength of themselves. Even if it is only a small success, cheer for them loudly "You are great". Because children's success is never too small to praise, every small success is the cornerstone to guide them to the next success. Of course, children don't always succeed. In the face of their failure, we should praise their efforts, help them analyze the reasons for their failure and encourage them to strive for the next success.
