Using Sigmund Freud's model of the unconscious, this book describes what is incorrect about the common way of thinking about the unconscious process known as the self. The ego is the decider for the self and it's role is to balance the desires and appetites of the id against the rules and regulations of the superego found in laws, religion, parental regulations of the family etc. If the ego functions properly, this results in a more balanced self and leads to happiness. The book also outlines some simple activities that a person can use to strenghten their ego to perform its crucial role for happiness in the individual.
