Carte - How One Idea Multiplied My Income and Happiness - Frank Bettger

May I suggest to all salesmen taking our course that you borrow a copy from your public library.Better still, buy a copy at your local bookstore. I can recommend it with enthusiasm. When I started out to sell I would gladly have walked from Chicago to New York to get a copy of this book if it had been available at that time. That statement may sound like an exaggeration but I mean it literally. Dale Carnegie
