Each of us is visited from time to time by a desire to look into the head of another person. What is he thinking? What does he want? How do you feel about me? Suzanne Stabil's book is a guide to nine personality types and their relationships with each other. She teaches to understand people who are as unlike us as possible, and to understand their own motives, fears and restrictions. The author's system is based on the concept of enneagram - a model that describes nine types of personality and the connections between them. And also - it helps to determine your own type and, if necessary, transform it into the desired one.
