This book was first published in 1937 when Napoleon Hill was asked to interview the most successful businessmen of the time (Andrew Carnegie, Thomas Edison, Henry Ford and other millionaires of his generation). Hill discovered 13 common elements of success. The book has been updated for the 21st Century by Arthur R. Pell, an American author, lecturer and human resources consultant. The book includes anecdotes of how modern-day millionaires and billionaires, such as Bill Gates, Mary Kay Ash, Dave Thomas and Sir John Templeton achieved their wealth. The outdated terminology and examples from the original book have been refreshed to remove any obstacles for a new generation of readers. The original version can be purchased as an ebook from iTunes for $0.99.
