Como Ganar Amigos E Influir Sobre las Personas

How to Win Friends and Influence People is a 1936 self-help book written by Dale Carnegie. Over 30 million copies have been sold worldwide, making it one of the best-selling books of all time.Carnegie had been conducting business education courses in New York since 1912. In 1934, Leon Shimkin, of the publishing firm Simon & Schuster, took one of Carnegie's 14-week courses on human relations and public speaking, and later persuaded Carnegie to let a stenographer take notes from the course to be revised for publication. The initial five thousand copies of the book sold exceptionally well, going through 17 editions in its first year alone.In 1981, a revised edition containing updated language and anecdotes was released. The revised edition reduced the number of sections from six to four, eliminating sections on effective business letters and improving marital satisfaction. In 2011, it was number 19 on Time's list of the 100 most influential books.
