Earl Nightingale said that he came to his "aha" moment at the age of twenty-nine while reading Napoleon Hill's Think and Grow Rich - specifically the words "we become what we think about". Shortly thereafter he recorded The Strangest Secret which went on to earn a gold record and became the largest selling non-entertainment recording in record industry history.
Think and Grow Rich is the standard against which all motivational books are measured. The book has helped millions of people create their own success and realize their dreams.
