A standing transfer set up on a Tuesday afternoon, a small amount at a time. Sunday dinners that happen whether or not anyone's in the mood. The habit of asking a teenager one real question instead of three logistical ones.
None of that feels like laying foundations. All of it is.
Optimism about what's ahead holds up better when it's fastened to something already running. Pick the one ordinary practice most likely to still exist in five years and protect that above any plan. It's doing more work for the people you love than anything you could write down.
