Very readable and interesting book. New science questions the traditional concept of external rewards. Interfaces well with The Talent Code, a current favorite book. My friend Dave read it and became inspired to initiate a very challenging project, building an F-4 mandolin. I am now even more fueled to go hiking, in fact, this week! The book explains why the typical incentive systems for teachers to improve will not work. Explains why I have “Megatex” tattooed on my calf. Surround yourself with the best folks that you can assemble, and let them loose: the secret to completing the Pacific Crest Trail.
