Motivation and inspiration energize people, not by pushing them in the right direction as control mechanisms do but by satisfying basic human needs for achievement, a sense of belonging, recognition, self-esteem, a feeling of control over one's life, and the ability to live up to one's ideals. Such feelings touch us deeply and elicit a powerful response.
Leaders establish the vision for the future and set the strategy for getting there; they cause change. They motivate and inspire others to go in the right direction and they, along with everyone else, sacrifice to get there.
Producing major change in an organization is not just about signing up one charismatic leader. You need a group - a team - to be able to drive the change. One person, even a terrific charismatic leader, is never strong enough to make all this happen.
