* Our summary is short, simple and pragmatic. It allows you to have the essential ideas of a big book in less than 30 minutes.

*By reading this summary, you will discover that your personality is in perpetual movement between several states of mind.

*You will also discover : that each person experiences eight so-called "motivational" states; that each of these states has its opposite, which explains human contradictions; that human behaviors seem paradoxical but are not irrational; that your contradictions help you to blossom in different areas.

*For a long time, psychologists thought that the human personality was immutable, fixed for life. However, this idea was overturned by the theory of reversal in the 1970s. This theory assumes that your personality oscillates between different values and motivations. It is therefore complex and full of paradoxes. This explains why you take risks when you are in a comfortable situation, for example. It all depends on your deep-seated motivation, which is constantly changing. So how do you adopt the right state of mind at the right time?
