ABSTRACT
A person was metaphorically described as steering his or her life through various domains by means of an engine that receives energy from the person’s characteristics, goals and values, and mental well-being. Furthermore, individual differences in social and psychological functioning were described in a series of schematic models. The use of the metaphor and models does not mean that the conception of the human being in this book is mechanistic. The goal was to illustrate the core role of an individual as an agent of his or her life.
