Query: A Con Job

Drosnin says he learned about this from the smartest man he ever met. WRONG! The smartest man he ever met was his publicist, probably himself.This book is nothing more than a random walk and a con job. Save money and interpret cumulous clouds for free. He is probably laughing at his followers. Do a google on him and all will be confirmed.
