The most important thing to know is what you do not know. This is a statement that applies to the role of leadership. But actually, as is often the case, it applies at the most fundamental level of existence. When you consider the operating software of your life, you must consider, first of all, its limitations. I have allowed myself over many years to be pleasantly deceived. I could not face not knowing what I did not know. As I have come to face as much of it as I can bear, I realize its binary impact on every moment.
