"When we are not sure, we are alive." - Graham Greene
Life is uncertain because the future is unknown. While uncertainty is an essential part of living, it is also the primary source of our anxiety. We are most anxious when our future is especially unpredictable, precarious and surrounded by danger. Consequently, we do all we can to fashion order and predictability. In spite of our best efforts, however, life remains uncertain and we are never sure. But we are alive! To have absolute certainty about tomorrow is to be dead, for when we are dead, there are no more surprises and no more decisions with unknown consequences. The good news is that uncertainty always contains new possibilities while absolute certainty offers neither possibilities nor opportunities for creative expression. Facing an unknown future is the very essence of life, without which there can be neither satisfaction nor fulfillment.
