Effective leadership is putting first things first. Effective management is discipline, carrying it out.
Not the cry, but the flight of a wild duck, leads the flock to fly and follow.
My own definition of leadership is this: The capacity and the will to rally men and women to a common purpose and the character which inspires confidence.
All of the great leaders have had one characteristic in common: it was the willingness to confront unequivocally the major anxiety of their people in their time. This, and not much else, is the essence of leadership.
John Kenneth Galbraith
He who has great power should use it lightly.
The leader has to be practical and a realist yet must talk the language of the visionary and the idealist.
Leadership is a potent combination of strategy and character. But if you must be without one, be without the strategy.
You manage things; you lead people.
Rear Admiral Grace Murray Hopper
Men make history and not the other way around. In periods where there is no leadership, society stands still. Progress occurs when courageous, skillful leaders seize the opportunity to change things for the better.
Harry S. Truman
To do great things is difficult; but to command great things is more difficult.
