Call it intimate or egocentric, Jurgen's writing style is ultimately personal. Being renowned as one of the top influencers in the Agile community, he uses himself as an example or reference all over the book.
Personal marketing aside, as the book is sold as a compilation of management best practices, the amount of learning and enjoyment you can take out if this book will really depend on what you have already experienced. Some chapters may read as old news, shallow cognitive psychology, or blunt statements lacking evidence. But others may look as the path to enlightenment, a stroke of genius, a collection and wise and well-thought advice to empower you and your business. Just remember Jurgen's own warning: Apply the practices in your own unique way.
Personally, I found the Metrics Ecosystem chapter really useful. Salary Formula, Merit Money, and Yay! Questions and Celebration Grids were also informative and inspiring. I also got curious about playing the Moving Motivators game.
His closing thoughts about value stream vs. value network, and customer-value principle vs. a social network of people generating value for each other are by themselves worth a new book!
