The author says that the characteristic of people whose lives are going well is that they have high "self-esteem." Self-esteem is the heart that tries to cherish oneself. People with self-esteem are always full of confidence, and even if they make mistakes or errors, they have the mental space to take it positively and use it as the foundation for the next step. Self-esteem has a great influence on almost all aspects of life.
