“Pay attention to what’s in front of you – the principle, the task, or what’s being portrayed.” Marcus Aurelius, Meditations
Allowing your mind to wander unrestrained to thoughts about a future that has not yet happened or to a past that cannot be regained deprives you of the wisdom of now. Keep in front of mind what it is you are doing right now and why – informed by the past and motivated possibly by the future, but very much alive in the here-and-now.
