“You don’t have to do something forever, for it to have been worth doing.”
That was the advice I received long ago from a friend, and it helps tremendously.
Here, for instance, is a display of santas on the mantle of our house. The photo was taken today, 31-Dec-2022. A person who is familiar with our household traditions may notice that the tall santa on the left is new this year and thus be able to date the photo. These santas occupy the mantle during the month of December, and come the new year they will be carefully removed, packed away to the next December, to be enjoyed again.

So, we have a mix of the temporary (the presence of santas on the mantle), the periodic (every December), and the permanent intention (bring out the santas every Christmas). It turns out that the question “how long should the santas be displayed on the mantle” has a complicated answer. Life is like that.
If something is worth doing, do it if and when the circumstances seem appropriate. You do not have to do it forever. You do not have to be correct, either. Life is full of learning opportunities.
