It is a theory of behavior, evolved from systems theory that is based on the premise that all our behavior is internally motivated to satisfy physical and/or psychological needs. This means that you have control over your actions intrinsically and not influenced by external or extrinsic factors. Glasser (1999) explains that all we do in our lives is behave well and that we choose our behavior in an attempt to satisfy one or more of the five basic human needs that are embedded in our genetic structure: belonging, enjoyment, freedom. , power and survival.
