Before Oprah Winfrey, 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.""""

What he discovered was as simple as it was profound: understanding people's needs and desires is paramount in any successful enterprise.
