In other words, ask questions and try to learn. Shut up and listen. Nobody cares about your solution. They care about sharing their pain and frustration. If you know and understand their pains and stop focusing on your own solution, you will also be able to help with other strategies and build more meaningful relationships. If you want to increase sales, there are many ways of how to do it. If you say, increase the sales team, most people will show you the door.
Were you able to sell something to a client multiple times without understanding them? If yes, please share how :)
