Query: Mind-blowing!!! Prep yourself for a HUGE paradigm shift!!

Having heard about this book well over a year ago, my only regret is not getting it much sooner. It's a quick and easy read, and the principles taught within its fictional story are astounding! It is definitely the most important book I've ever read for my industry. A MUST-HAVE for anyone in sales of any kind!!! Five stars is not enough!
