Doctor of social psychology, founder and president of the International Society for Peace through Culture named after N.K. Roerich, Professor P. Weinzweig wrote an unusual book. Designed for the general reader, the book is at the same time of interest as a scientific work on psychology. The author promotes extremely important things. It is no coincidence that the original publication published in Canada has the subtitle “How to Achieve Happiness and Success.” Is it really possible to achieve this? How to overcome various life difficulties and adversities? How to develop creativity? How to live in peace with the people around you? How to deal with stress? How to help yourself in a hopeless situation? In answering these questions, P. Weinzweig’s book can become an excellent assistant and interlocutor. Central to it is the concept of “Personal Strength,” which is characterized by the ability to overcome life’s challenges, the presence of self-control, and the harmony of natural-physical and spiritual goals and values. The book examines in detail these components of the Power of Personality.
