This was more of a resource book sighting endless studies done by others spanning over the last 100 years. The author, who is rather excessively long winded and wordy seems to care more about his writing style and sounding intelligent- blathering endlessly on with an unnecessary over use of big worlds and data- then getting to any useful point. The author leads you down a path of dangling carrots to buy his cassette tapes and schedule an appointment with him for the insights and answers you thought you would find in this book. A huge disappointment!!! Nothing revelatory here.
