The Theory of Seven Selves is psychology as it should be: simple, clear, without abstruse words. This is the doctrine of the seven inner selves, from which the character of a person is formed, 7 mental types and 7 roles of the collective are born. The 7Self theory is a powerful tool for understanding the inner world: it makes it possible to understand oneself and others, to find hidden selves in the depths of the soul, to turn one’s character traits into competitive advantages.
