Salesman

In this documentary (which I only saw half) I could see how hard the life of a salesman was back in the 60's and to make a few bucks they have to go door to door and not take no for an answer. And it is not like they were selling candy or toys or anything that people had familiar background about, this was a book that could change your way of thinking and offer something completely new to you and open your eyes to a new world and even in modern day people don;t like to change so it seems like a tough life to be doing.
