The ideas presented in the book are honestly not revolutionary but they make a good theme.
1. Absolute Clarity of Purpose.
2. Empowered Obsession.
3. Unleashing Creativity.

The experience sharing is thorough but the book lacks an action plan.
The author is basically recounting and dissecting his experience in these exceptional organization but it does not differentiate with how many million companies out there who are adopting similar ideas but fail to make the cut.

It's a good to read if you are free book but nothing ground shaking or deep insights that i can gather for my own use beyond these ideas.

A really different, personal and inspiring take on leadership.
