Your work is a Godsend!

I’ve been reading, and using, your information since I first read the ‘Little Red book of Selling’. I’ve read, and continue to read your other books, ‘21.5 Laws of Selling’, ‘Very Little, but very powerful, book on closing’ and of course your latest ‘Sales Manifesto.’ All signed but the last one. The information they provide continues to make me a better sales person. I will continue to implement your teachings as I strive to give my customers the quality selling/consulting experience they deserve. Thanks again and I’ll always remember. “It takes sales balls to make sales calls”
PS - Are there any recommendations you have for door to door sales?
