A response from Jonah Udall:
Maybe this is an unsatisfying answer to many, but I cope with uncertainty by recognizing its essential-ness. Instability, change, is a fundamental characteristic of existence. To live in this truth is a deep peace. Certainty is intoxicating, enticing, but also nerve-wracking, because in the deepest core of our being we know it to be false. I work every day to unlearn the myth and live more fully in the mystery.
