The reason I’m giving this book and single star and requesting a refund isn’t so much the main content, even though it was disappointing at best. Rather my negative review is earned through the 2.5 hour afterward the author chose to include. Instead of being new insight or information, this addition is simply hours of the author whining that someone disagreed with their conclusions. Perhaps the author is unfamiliar with the world, but differences of opinions are commonplace and to just continually cry about how you are right and this other person was wrong was very off putting.
