Understanding the Level of Ego Development of the Used Car Dealership

Before this model, before spile dynamics, before you knew developmental psychology, which is what this is, you interacted with people in the world. You didn't understand the level of their ego development. But now, once you understand this model, and especially once you go through many of these stages yourself, you can see very clearly where the people you're dealing with are at. This is one of the most useful functions of this model.
