Freely adopting appropriate ways of being, for example, to match the reality of the people you are with, is a necessary social skill and all part of the fun and variety of life. By self-observation, you will catch yourself lying. In fact, people do not even know who or what they are. Even when he has no choice and is controlled in life like 'a reed in the wind', a person will lie to himself that he is self-willed, knows himself and is in control of his destiny. You imagine these things to please yourself, and shortly after you begin to believe it.
Some people take pride in their irritability, anger or worry.
It is extremely difficult to perceive that you actually enjoy negative emotions. Books, movies, TV and popular songs glorify negative emotions such as anger, fear, guilt, boredom, disgust, irritation, hatred, jealousy, suspicion, self-pity, sympathy, depression, etc. Many people are controlled by the expression of negative emotions. Negative emotions and all habits require 'identification' or they cease to exist. Habits cannot be stopped by willpower, they can only be erased by self-knowledge.
