In short read it, with controlled expectations.
The contents of this book can be concentrated down to 15 to 20 pages too. Rest is Cardone, Bowing to Cardone along with yes a few great personal tips of his own and some great stories. This is also a segway to sell his seminars. First 50 to 80 pages are "you can do it if you do it like this" motivation.
Why He doesnt label the tools? Empathy, nurturing, listening and memorising, probing questions etc? Is beyond me.
