Despite the years, the works of Pierre DACO have not aged. The presentations are of great clarity and guidance of great practical use to understand the behavior, starting with his own. They are true guides for the elaboration of exchanges with others. The book is of great simplicity in the use of terms and the presentation, without missing the needs of information. The book is a discovery for the uninitiated and a real working tool; both in introspection of the drive in the understanding of his relationship with others and the behavior of humans; be they children, family, or strangers encountered in the work and in everyday life.
