Freud believed that personality or human spirit is mainly divided into three basic parts, namely ID, ego and superego. Freud divided people's motives into hunger, thirst, sleep and sex. Among them, sexual desire is dominant (ID). However, the ID is often restricted by realistic conditions such as morality, social regulations (superego), depressed and unable to escape, and seeks satisfaction through dreams, aphasia and other forms. Freud believes that if a person has had some traumatic events before and caused psychological problems, as long as he can consciously repeat them and balance ID, ego and superego, the problem will be solved.
Personally, Freud's theory is unscientific. The only scientific way to strengthen your personality health is to change yourself for yourself and others at the same time and make yourself more and more perfect.
