A key message that I get from this book is the rules as simple as they seem, but at the same time it could be misleading to say these rules apply to only a small scope in life. Was expecting a somewhat productivity or self help book. This book is geared more towards philosophy and self development.
The writer does who good job in broadening the scope of each rule and then returns to its main message in the end. One might say that the writer pushed his right wing ideologies a bit too much in this book. but its his book. He explained his thinking, we chose to listen. As in rule 9, Assume whoever you're listening to knows something you don't.
