Title: Before you buy this book...
Product review: ...ask yourself a few simple questions. Why did da Vinci accomplish what he did without any self-help books? Why Mr. Gelb, who claims to have deciphered da Vinci's alleged "principles of genius," hasn't created a work of art that will last millennia? Why hasn't he made an invention decades ahead of its time? Is this all he can do with the arsenal of mental powers he claims to have discovered? Write a $11.17 self-help book? A bit of a letdown, perhaps? Answer these questions and you'll know if you need this book.
