The book is devoted to solving the problem of maintaining the psychological health and well-being of a person by setting up a special system of mental self-regulation. The system-forming factor in the formation of such a system is the self-actualizing tendency of a person. The process of realization of this tendency is described in the work by the interaction of three mental substructures: creative and essential - essential, secondary and destructive - infernal, as well as choosing and decisive - "Ego". The idea of "mental tone" of the bodily-emotional, communicative and behavioral parts of the human self-regulatory system is revealed, and therapeutic strategies for their adjustment are given. The book presents a diagnostic technique and a program for correcting personal responsibility as an integral property of a person's mental self-regulation. 
 The book is addressed to practicing psychologists and psychotherapists; students studying in the specialty "Psychology"; as well as to a wide range of readers interested in personal growth and self-development.
