Excellence is a better teacher than mediocrity. The lessons of the ordinary are everywhere. Truly profound and original insights are to be found only in studying the exemplary.

The basis of leadership is the capacity of the leader to change the mindset, the framework of the other person.

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."

I am reminded how hollow the label of leadership sometimes is and how heroic followership can be.

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

Don't over-react to the trouble makers.

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.
