Teach us to number our days, the psalm says, that we may gain a heart of wisdom. This sounds like a morbid instruction. A reminder of death. A dark cloud over an otherwise nice Tuesday. But it is actually the most liberating principle in the entire wisdom tradition.
When you realize your days are numbered, something remarkable happens to your priorities. The things that drain you lose their grip. The obligations that exist only because of guilt suddenly seem optional. The activities that fill time without filling your soul become clearly, undeniably wasteful.
Numbered days do not create anxiety. They create clarity. If you have a finite number of Tuesdays left, do you really want to spend them in a meeting that could have been an email? If your weekends are limited, do you really want to spend them catching up on work? If your evenings with your family are countable, do you really want to scroll through your phone during dinner?
Finite time does not demand that you do more. It demands that you do less, better. That you invest your limited days in things that actually matter and stop hemorrhaging them on things that do not. Rest is one of the things that matters most because it is the thing that makes you present for everything else.
If your days are numbered, and they are, what changes about how you rest? What commitments are no longer worth your finite hours? What would you stop doing today if you truly internalized that this day will never come again?
