I have been reading The Fifth Discipline by Peter Senge as part of the Agile Austin Book Discussion Group, and one quote struck me as particularly meaningful from Lao Tzu:
The wicked leader is he whom the people revile.
The good leader is he whom the people revere.
The great leader is he of whom the people say, "We did it ourselves."
To me, the "great leader" succinctly describes what it means to be a servant-leader--what do you think?
