While most books about selling focus on the salesperson's behavior, this book focuses instead on the client's behavior and the sales approaches you should use depending upon just how weird or annoying - excuse us, that should be "challenging" or maybe "eccentric" - the client becomes. Josh Gordon clearly and effectively presents 20 different classic, difficult behaviors, including everything from "The Client Who Lies to You" to "The Client Who Knows It All." Gordon offers useful strategies for dealing with such personalities and situations, strategies that can help you make your sale and then make a clean getaway. The book is written conversationally and includes no filler or fluff, just plenty of well-organized and helpful ideas. We [...] recommend this book to anyone who has to sell a product, service or idea, because sometimes it is nice to know that you aren't the problem.
