The question of leadership has always been a crucial one for human society. Whether in politics, business, or education, thoughtful people have always asked, 'What makes a good leader?' In 1970, with the publication of his now classic essay The Servant as Leader, Robert K. Greenleaf answered this question with a revolutionary idea whose influences continue to be felt strongly to this day. Greenleaf proposed that truly great leaders are not motivated by the selfish desire to increase their own power or prestige, but by a yearning to help others. In other words, a great leader is, first and foremost, a servant to others.
