The woman next to me adopted a serious expression, and her voice sounded determined. It was the voice of someone who, after a long period of reflection, has finally made a decision: "I want to finally become an adult." In order to fully understand what it psychologically means to be an adult and how we reach adulthood, it is helpful to revisit the differences between the awareness of a child, a teenager, and an adult.

The book carefully describes and examines the most important stages of our lives and the internal and external life conditions that apply at each specific stage of development. In each of the 7 stages of development, we have a different sense of life and a different awareness of ourselves, our immediate surroundings, and the world as a whole.

This different consciousness guides us in the corresponding state of our life and helps us to act and behave appropriately. In each of the 7 developmental phases of life, there corresponds a different personal consciousness: Prenatal, Childhood, Adolescence, Adulthood, Mature Adulthood, Old Age, Death.
