I have not read this book yet, but chose it because it seemed interesting, as well as extremely popular, with a readily available Audible version for those who prefer listening to a book. I am curious to discover if the book resonates with me, and you, or not, and if not, why not. Some of the negative reviews of the book question the author's motives, training, process, professionalism, and validity. I enjoy some healthy skepticism, don't you? It makes me want to read it all the more.
