Authority by giving it away.

Leadership must be based on goodwill. Goodwill does not mean posturing and, least of all, pandering to the mob. It means obvious and wholehearted commitment to helping followers. We are tired of leaders we fear, tired of leaders we love, and tired of leaders who let us take liberties with them.
What we need for leaders are men of the heart who are so helpful that they, in effect, do away with the need of our jobs. But leaders like that are never out of a job, never out of followers.
Strange as it sounds, great leaders gain authority by giving it away.
