ABSTRACT
The issue of how to understand and influence human motivation has proven to be one of the most recalcitrant problems in human psychology. The fundamental reasons for this are that motivation at root comes from within the individual and is most directly controlled by the individual. Since motivation is "inside" the person, it cannot be observed directly, and since individuals possess freedom of choice-that is, free will (Binswanger, 1991)—people cannot be controlled directly from the outside.
