The principle that I’d blown right past in my pursuit of creative invincibility was that each commitment I made, and each project I decided to take on, required something more of me than just my time. Each required my energy. And because I was not being strategic and purposeful about the number and nature of simultaneous commitments I was making, I soon found myself in energy debt. I was creatively inverted and no longer had enough energy to generate the ideas I needed just to keep my head above water.
When you are planning your life, you need to account for every commitment you make in every area.
