Most people have a tendency to talk too much and listen too little.
Yet, by reversing this common practice you have a great advantage in any conversation that allows you to discover what it's going to take to get that person to agree with your point of view. To illustrate, consider the very unhappy experience I had while shopping for a new car. The odd thing was that after the experience I discovered I was not alone. At the time, I was driving a big luxury car and thought it was time to buy a sports car. A close friend had a very nice sports car and let me drive it a couple times.
