Protect yourself from harmful thoughts.
Sometimes we develop firm erroneous beliefs, which are extremely difficult to overcome. It seems to you that they are a part of you, but they are not. A person is plastic by nature and can accept any attitude if he forms it long enough and persistently. This ability can be useful. Track down the beliefs that prevent you from living: low self-esteem, lack of opportunity for change, and so on. Ask yourself questions, become your own psychiatrist. For example, if you feel uncomfortable in the company, ask yourself: "Why did I decide that shyness is my natural quality?", "What prevents me from communicating freely?", "Have I always felt squeezed in the company of other people?", "When did it start?".
