In this classic of personal-success literature, Napoleon Hill presents the results of his 25-year study of more than 500 wealthy and successful people. He distills the findings into thirteen principles (such as Desire, Faith, Autosuggestion, Decision) that, if understood and acted upon, can lead to wealth and success. The revised edition updates these ideas with contemporary examples of achievers such as Bill Gates and Steven Spielberg to show how the principles remain relevant today.
