Leadership is like beauty - it's hard to define but you know it when you see it.

Don't over-react to the trouble makers.

The leader...is rarely the brightest person in the group. Rather they have extraordinary taste, which makes them more curators than creators. They are appreciators of talent and nurturers of talent and they have the ability to recognize valuable ideas.

Coaching will become the model for leaders in the future... I am certain that leadership can be learned and that terrific coaches... facilitate learning.

If great teams don't have an "enemy," they create one for themselves because, as former Coca-Cola CEO Roberto Goizueta pointed out, "you can't have a war without one."

Leaders wonder about everything, want to learn as much as they can, are willing to take risks, experiment, try new things. They do not worry about failure but embrace errors, knowing they will learn from them.

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.
