What do you do when you want to listen well?

When you listen well to a person, what exactly do you do? And what do you not do? What does it mean to really listen well? In situations during which you listened well or experienced that the person listening to you listened well, what was characteristic of the way you and/or others listened? When you reflect upon the way you listened to someone today, what did you well, and what do you think you could do better to become an even better listener?
