Managers and Leaders

The manager is more tightly linked to an organization than is the leader. Indeed, the leader may have no organization at all. Florence Nightingale, after leaving the Crimea, exercised extraordinary leadership in healthcare for decades with no organization under her command. Gandhi was a leader before he had an organization. Some of our most memorable leaders have headed movements so amorphous that management would be an inappropriate word.
