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

Growing other leaders from the ranks isn't just the duty of the leader, it's an obligation.

Create a compelling vision, one that takes people to a new place, and then translate that vision into a reality.

Every great group is an island... but an island with a bridge to the mainland.

Recognize the skills and traits you don't possess, and hire the people who have them.

Leaders learn by leading, and they learn bestby leading in the face of obstacles. As weather shapes mountains, problems shape leaders.

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.
