Forget lengthy presentations and long-meetings. Get things half done, in half the time, and involve people in your solution to get better results. In the book, 18 Minutes: Find Your Focus, Master Distraction, and Get the Right Things Done, Peter Bregman shows you how to shoot for imperfection to get your ideas and solutions adopted.
If you want somebody to listen to you, you need to first give the other person some psychological air. Listen until the other person feels understood, affirmed, validated, and appreciated. You can do so through empathic listening. Once the other person has their psychological air, they’ll be ready, willing, and more able to listen to you.
