There are many benefits to good listening. The more you really hear what others are expressing, the better you can understand other people and their needs. The better you understand their needs, the more you can choose to facilitate those needs being met. A genuine desire to understand the people in your life leads to increased intimacy while encouraging other (by example) to try to listen to and understand you. The result is that your relationships will significantly improve.
