Stay in the moment.
You know I love this one! When you devote your full attention to the person or people you are communicating with, you're more likely to have much better results. I know for a fact that's very, very true. Whenever I've gotten distracted and stopped paying attention to the person I'm communicating with, the communication as quickly gone south. If you want to communicate your thoughts effectively, you have to stay in the present moment and really be there when you're speaking and listening.
