In the Christian liturgical calendar tomorrow is the last day of the year, with a new year starting on Sunday in Advent. All wisdom and religious traditions give guidance on how to work with the passing of time, how to celebrate fully and be complete in each moment which we have. This text is from the Stoic philosophical viewpoint:
Let us prepare our minds as if we had come to the very end of life. Let us postpone nothing. Let us balance life’s books every day..The person that puts the finishing touches on their life each day is never short of time.
Seneca, Moral Letters, 101, 7b – 8a
