This was the first book on leadership I've read. There is a wealth of useful knowledge, tips and prompts for self-reflection in it. Only sometimes it tries to be too concise and dense when presenting information, which results in abstract - therefore less helpful - descriptions of models or rules. Another aspect I definitely could have done without was the Buddhist spiritual stuff which gave parts of the book a worryingly irrational streak. Example sentence: "Follow your intuition and rationalize your actions afterwards." Probably the last thing humanity needs in this new world with growing challenges and threats is irrational leaders who don't think before they act. You can skip over those passages, though, and focus on the useful parts: overall I can definitely recommend the book.
