This book will be a great addition to any teachers, managers, or parents bookshelves. It explores the psychology of intrinsic (vs. extrinsic) motivation and shows how supervisors, and other people in "one-up" positions, can be more than managers, but true leaders who foster autonomous, authentic growth and responsible decision-making in their subordinates. A must read for anyone who recognizes the lack of responsiblity and accountability in people today and would like to foster positive change in our schools, our companies, and our society.
