Through the "ego states" (the "Child", the "Adult" and the "Parent") that everyone has in itself Bernes exposes the mechanics of human interaction (mainly parent / subsidiaries, authority ), and how they impact any particular individual during infancy, writing for each of us a "scenario" of life more or less enviable, winner or loser (as to lead his life or suffer).
If you feel that things never seem to go your way or they do not go as they "should" go, reading this book could be a real awareness allowing you, perhaps with help of a therapist, correct your scenario to a more peaceful existence blossomed.
A reading which probably contributed to change my life.
