What kind of activity do good sales people do?

Good sales people build good relationships first by questioning and finding their interest. Then, they stat discovery questions. They don’t start product presentation until they finish discovery and find a space to listen in their customers. When they give some discovery questions they often use SPIN. S stands for situational questions, P stands for problem questions, I stands for Implication questions, N stands for need questions. 
When they talk about their products they always how this product solves customers problems. They mention “You” or customer name frequently so that the customer imagine how they can change by that product.
