Query: Really? His PhD is no longer valued

First and foremost, this author has been married several times. He clearly has know clue about making things last. Finally, his university where he obtained a PhD is no longer accredited. That says a lot about him and the information in this book. Life does not have a one fit all solution. We are better of taking information from someone who practices what they preach.
