Think and Grow Rich was written in 1937 by Napoleon Hill. Hill details 13 "steps" in which one can succeed not only monetarily, but in any line of work. Napoleon Hill discusses his time spent with some of the richest individuals of the United States (Andrew Carnegie, Charles M. Schwab, Henry Ford, among various others). He goes into further detail explaining the "Carnegie Secret" and how many billionaires in the US have followed this philosophy. Having sold over 100 million copies worldwide, Think and Grow Rich is arguably the best self-help/personal success book, that many millionaires have accredited their success to.
