It is paradigm-shifting to consider that using the Wheel of the Year (the cycle of the seasons) to mark a year-beginning and year-end means that the year begins with darkness and rest as the light wanes, and ends after the final harvest.
First: rest, recover, sift through all that you did over the previous twelve moons. Consider your mistakes — what can be learned? Can you accept that the choices you’ve made cannot be unmade?
Then: see the next twelve moons stretching before you, and take comfort that there are new choices ahead and that taking time for consideration before choice-making is part of the natural way of the world.
