Hear the silence
The importance of listening is well established, but what is often not realized that the most effective for of listening involves paying attention to what someone is not saying, as well as what they are saying. Just as silence is an important part of music, working out what is not being said is a key part of genuinely connecting with people, of forming an effective rapport. To hear what is not being said involves tuning in to the situation, considering the context, the emotions involved, where the conversation is coming from and where it is going. These are quite advanced skills, but they can be developed over time.
