This is not intended to be a how-to book or an all-inclusive text.  It is not likely you will become proficient in High Probability Selling merely by reading about it.  However, there are some salespeople who do.  Learning High Probability Selling generally requires many hours of rigorous interactive training, a desire to excel and to enjoy what you do.
