Many sales people set their goal to make as much money as possible.

This is a fantastic goal for a salesman, and often it is perceived that to achieve this goal you must extract the largest amount of money from a customer per visit. However, in most cases, this isn’t the optimum path to making as much money as possible (which to some may seem counter intuitive). The way to optimise the amount of money you can make per customer is to provide them with the most value per visit. By providing value, you create the revenue stream that will ultimately flow back to the sales person creating it. By focusing purely on extracting as much money as possible per customer, you may be draining the water from the land such that nothing will grow there ever again.
