Grant Cardone's Perfect Sales Process  

For fifty years, there has been very little change in how people sell things. Most of the information is dated, with encouragement to control the customer and spend long periods of time with them, believing the longer you spend with them the more indebted they become. The reality is that people have changed over the last fifty years, so the sales process must change with them.
