by Ronald Heifetz and Marty Linsky

This is the best book I've read this year. I started reading it with pen in hand, underlining key ideas. Then I was bracketing whole paragraphs, and resisting the temptation to bracket whole pages. Every page is like that. A great work on life and leadership that should be read by everyone who is any capacity of leadership... leaders of schools, business, churches, communities, or even of families. This is highly recommended (by me).
