”…During our ten-year association, I learned the missing number to my combination for worldwide successful achievement. The Master Mind Principle: two or more persons working together in complete harmony toward a mutual goal or goals…Napoleon Hill’s philosophy teaches you what you were never taught. Specifically: How to Recognize, Relate, Assimilate and Apply principles whereby you can achieve any goal whatsoever that doesn’t violate Universal Law – the Law of God and the rights of your fellowman…” —W. Clement Stone Chairman, Combined International Corporation President, The Napoleon Hill Foundation

”During the past twenty-five years I have been blessed with more good fortune than any individual deserves but I shudder to think where I’d be today, or what I’d be doing if I had not been exposed to Napoleon Hill’s philosophy. It changed my life.” —Og Mandino, Author and Lecturer

”I knew Napoleon Hill in 1922 when I was a student in Salem College in the town of my birth. Mr. Hill came to our campus as the commencement speaker in that year. As I listened to him, I heard something other than just the words he spoke, I felt the substance – the wisdom – and the spirit of a man and his philosophy. Mr. Hill said ”the most powerful instrument we have in our hand is the power of our mind.” Napoleon Hill compiled this philosophy of American achievement for the benefit of all people. I strongly commend this philosophy to you for achievement and service in your chosen field.”

Napoleon Hill (October 26, 1883 – November 8, 1970) was an American author in the new thought tradition of the previous century, and an early producer of personal-success literature. At the time of Hill’s death in 1970, his best-known work, Think and Grow Rich (1937) had sold 20 million copies. Hill’s works insisted fervid expectations are essential to increasing one’s income. Most of his books were promoted as expositing principles to achieve “success”. Hill was an advisor to two presidents of the United States of America, Woodrow Wilson and Franklin Delano Roosevelt. 
In every chapter of this book, mention has been made of the money-making secret which has made fortunes for more than five hundred exceedingly wealthy men whom I have carefully analyzed over a long period of years.The secret was brought to my attention by Andrew Carnegie, more than a quarter of a century ago. The canny, lovable old Scotsman carelessly tossed it into my mind, when I was but a boy. Then he sat back in his chair, with a merry twinkle in his eyes, and watched carefully to see if I had brains enough to understand the full significance of what he had said to me.

When he saw that I had grasped the idea, he asked if I would be willing to spend twenty years or more, preparing myself to take it to the world, to men and women who, without the secret, might go through life as failures. I said I would, and with Mr. Carnegie’s cooperation, I have kept my promise.

This book contains the secret, after having been put to a practical test by thousands of people, in almost every walk of life. It was Mr. Carnegie’s idea that the magic formula, which gave him a stupendous fortune, ought to be placed within reach of people who do not have time to investigate how men make money, and it was his  hope that I might test and demonstrate the soundness of the formula through the experience of men and women in every calling. He believed the formula should be taught in all public schools and colleges, and expressed the opinion that if it were properly taught it would so revolutionize the entire educational system that the time spent in school could be reduced to less than half.

His experience with Charles M. Schwab, and other young men of Mr. Schwab’s type, convinced Mr. Carnegie that much of that which is taught in the schools is of no value whatsoever in connection with the business of earning a living or accumulating riches. He had arrived at this decision, because he had taken into his business one young man after another, many of them with but little schooling, and by coaching them in the use of this formula, developed in them rare leadership. Moreover, his coaching made fortunes for everyone of them who followed his instructions.

In the chapter on Faith, you will read the astounding story of the organization of the giant United States Steel Corporation, as it was conceived and carried out by one of the young men through whom Mr. Carnegie proved that his formula will work for all who are ready for it. This single application of the secret, by that young man— Charles M. Schwab— made him a huge fortune in both money and OPPORTUNITY. Roughly speaking, this particular application of the formula was worth six hundred million dollars.

These facts— and they are facts well known to almost everyone who knew Mr. Carnegie— give you a fair idea of what the reading of this book may bring to you, provided you KNOW WHAT IT IS THAT YOU WANT.
 
Even before it had undergone twenty years of practical testing, the secret was passed on to more than one hundred thousand men and women who have used it for their personal benefit, as Mr. Carnegie planned that they should. Some have made fortunes with it. Others have used it successfully in creating harmony in their homes.
