It was an interesting book. The Art of War is a classic, but even if you're not interested in military strategies (like I'm not), this book can give you some food for thought. The point of view is interesting, as Sun Tzu's teachings are approached from a modern angle. The annotations provide ideas on how you can use the teachings in modern business life or in personal endeavors.

I read this book as an e-book, and it made moving between the text and the annotations quite easy.
