Psychology is an interesting and very useful science. After all, it does not study anything, but the mental activity of a person, by which we understand the many different processes that take place in our consciousness and subconscious. Man has always been a mystery to himself. And to a large extent it remains so today. We still know too little about ourselves and cannot always and with high accuracy explain and predict our behavior, as well as influence it in the right way. There are no magic buttons in us either, or we have not yet found them, by clicking on which, a person can immediately change himself or change others in the right way. Everything in us is much more complicated. But despite all the mystery of the human soul and mind, psychology has made significant progress in the field of knowledge of the essence of man.
