All great leaders constantly seek new information and new ways of thinking.

Encourage dissent: Leaders should have associates who have contrary views, who are devil's advocates, "variance sensors" who can tell them the difference between what is expected and what is really happening, between what they want to hear and what they need to hear. There are too many naked emperors running around today.

If you're the leader, you've got to give up your omniscient and omnipotent fantasies - that you know and must do everything. Learn how to abandon your ego to the talents of others.

The manager has a short-range view; the leader has a long-range perspective.

Our tendency to create heroes rarely jibes with the reality that most nontrivial problems require collective solutions.

Leaders know the importance of having someone in their lives who will unfailingly and fearlessly tell them the truth.

Good leaders make people feel that they're at the very heart of things, not at the periphery.
