Query: This review is for the audiobook

Most of the content is great, albeit Mr. Tracy seems to have a hyper-ambition about how much money one earns. Unfortunately, I had a hard time listening to Mr. Tracy's delivery of the material; it is very monotone and dry. If he could add some humor and excitement into his delivery, listening to the audiobook would be a much more pleasurable experience.
