Somebody mopped that floor before you got there. Noticing them is a habit worth building.

Most of what makes a day work was done by people you never see. The floor, the bus running, the shelves full, the building warm, all of it is somebody’s shift, and the better it is done the less visible it becomes. Not noticing is the natural result of good work rather than a moral failing, but it leaves you living in a world that seems to run itself.

Look for one of them today and say something specific. Beyond the courtesy, it changes how a place feels to you when you can see the people holding it up.
