It is the capacity to develop and improve their skills that distinguishes leaders from followers.

Great groups deliver great results. And for everyone involved in a great group, great work is its own reward.

Leaders are people who do the right thing: managers are people who do things right. Both roles are crucial, but they differ profoundly. I often observe people in top positions doing wrong things well.

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.

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

People in great groups have blinders on. Their work is all they see. They value failures as learning opportunities. They are optimistic, not realistic, as they proceed from one challenge and crisis to the next.

Without a terrific leader, you're not going to have a Great Group. But it is also true that you're not going to have a great leader without a Great Group.
