The preface to this book is written by 'Joe Girard', considered to be the 'best salesperson in the world' by Guinness Book of World Records. Interestingly I had come across Mr.Girard in the book Influence by Robert Cialdini (read my review here) where his example was used as to illustrate one of the tools of Influence - Liking. Apparently Mr.Girard sent thank you notes every month to each of his customers with the words 'I like you'. Amazing how the world is small after all.
May not be. Almost all the examples in this book are different variations of how sales persons use the six tools of influence as discussed in the Cialdini book. Maybe there is a connection there that I don't know.
