As a salesperson, you should be able to control a conversation. This does not mean that you should dominate the conversation, but you should be able to steer the direction in a way that will give you a better chance of making the sale. Many salespeople think that they need to just spit out a bunch of features and the customer will see how great their product is and buy it, these people are peddlers. A true sales professional takes as much time listening to their customer as they do talking, and there are certain steps you should take to present yourself and your product in a way that will make your customer want to buy.
