Here is the way Al-Anon explains the “one day at a time” mantra: “In most cases, we cannot anticipate every possible turn of events, and no matter how diligently we are prepared, we are eventually caught off guard. Meanwhile, we’ve expended so much time and energy trying to predict future events, soothe future hurts, and prevent future consequences that we have missed out on today’s opportunities. And the magnitude of the task we have set for ourselves has left us drained, overwhelmed, and distraught.”
