„If by motivation we mean whatever it is that causes someone to follow a particular course of action, then every action is motivated — by definition. But in most human behavior the relation between motives and action is not simple; it is mediated by a whole chain of events and surrounding conditions. We observe a man scratching his arm. His motive (or goal)? To relieve an itch.“
— Herbert A. Simon, kniha Administrative Behavior
