ABSTRACT
Effective leadership involves influencing others so that they are motivated to contribute to the achievement of group goals. This process lies at the heart of human progress. Scarcely any advance that civilization has made would have been possible without it-whether in arenas of politics and religion, science and technology, art and literature, sport and adventure, or industry and business. For good or for ill, leaders are widely recognized as the proper focus for our attempts to understand the tides and shape of history. As a result, from an early age, we are told wonderful stories about the role that great leaders have played in making history and initiating the changes that have created the world as we know it.
