ABSTRACT
American psychology professor, David McClelland, devoted 20 years to studying motivation and the human need for achievement before finally publishing his theory within Human Motivation in 1987.1 The conclusions he presented suggest that people aren’t motivated by the concept of reward. Rather, each person has three types of need that exist in differing degrees and it is the combination of these three factors that explains our individual levels of drive as well as our preferred sources of motivation.
