Before Stephen Covey, Oprah Winfrey, and Malcolm Gladwell there was Dale Carnegie. His book, How to Win Friends and Influence People, became a best seller worldwide, and Life magazine named him one of "the most important Americans of the twentieth century." This is the first full-scale biography of this influential figure. Dale Carnegie was born in rural Missouri, his father a poor farmer, his mother a successful preacher. To make ends meet he tried his hand at various sales jobs, and his failure to convince his customers to buy what he had to offer eventually became the fuel behind his future glory. Carnegie quickly figured out that something was amiss in American education and in the ways businesspeople related to each other. What he discovered was as simple as it was profound: Understanding people's needs and desires is paramount in any successful enterprise. Carnegie conceived his book to help people learn to relate to one another and enrich their lives through effective communication. His success was extraordinary, so hungry was 1920s America for a little psychological insight that was easy to apply to everyday affairs. Self-help Messiah tells the story of Carnegie's personal journey and how it gave rise to the movement of self-help and personal reinvention.
