So many successful people praise Napoleon Hill for what he has done throughout his life, for all the lives he has helped find the truest purpose in life and reach craziest dreams. And they are right to some extent for praising him because Napoleon Hill was truly one of the best masters of his craft, and he knew everything about the power of human unlimited or limitless potential, before anybody else did, and he has uncovered the secrets of the mind, and has shared them with the world. Of course none of that would have been possible if he hadn't interviewed Dale Carnegie who has supposedly shared all those secrets behind unlimited success with him, but that's a whole different story. This book comes highly recommendable to those who have read at least one of Napoleon Hill's books, and are pumped enough to read another one, for this is the kind of book that's kind of difficult to comprehend, if you don't already know the author's metaphorical style of writing.
