According to the philosopher Arthur Schopenhauer (1841/1960), to be motivated is to be moved into action, or to decide on a change in action. He was one of the first to speculate on the relationship between motivation and behavior. Action or behavior does not occur spontaneously but induced by either internal motives or environmental incentives. A motive is a person’s internal disposition to be concerned with and approach positive incentives and avoid negative incentives. Motivation describes the wants or needs that steers behavior toward a goal. Motivations are commonly classified into two types: drives are acts of motivation like hunger or thirst that have primarily biological purposes, while motives are fueled primarily by psychological and social mechanisms.
