One man’s belief in the power of self-transformation became a springboard to millions of success stories for more than a century. Stories of unforeseen confidence, unexpected team cooperation, and unprecedented business results show just how powerful a commitment to personal growth can be.

Dale Carnegie’s own story is equally surprising. Born into poverty in the small town of Maryville, Missouri, where he worked on the family farm, he grew up to be one of the most compelling speakers, revered business leaders and best-selling authors in the world. More than 50 million copies of Mr. Carnegie’s books such as How to Win Friends and Influence People and How to Stop Worrying and Start Living have been printed in 38 languages. As a result, more than 8 million lives have been inspired by his timeless values and practice.
