Every one of the geezers who continues to play a leadership role has one quality of overriding importance: neotony. The dictionary definition is that neotony, a zoological term, involves "the retention of youthful qualities throughout old age." It is more than merely retaining a youthful appearance, although that is often part of it. Neotony is the retention of all those wonderful qualities that we associate with youth: curiosity, playfulness, eagerness, fearlessness, warmth, energy.

Judgment without character is expediency... or worse.

The manager does things right; the leader does the right thing.

Leaders must encourage their organizations to dance to forms of music yet to be heard.

A passion for continual learning, a refined, discerning ear for the moral and ethical consequences of their actions, and an understanding of the purposes of work and human organisations

Trust is the lubrication that makes it possible for organizations to work.

This duality, making yourself better while teaching and developing others' judgment capabilities, is the key to leadership that is both productive and principled.
