The wrapper on the floor isn’t yours. Picking it up anyway is still yours.

Responsibility for a mess and responsibility for a place are different things, and most people only accept the first. Picking up something you did not drop is a quiet statement that the space matters to you beyond your own share of it. Nobody hands out that job. It exists only because somebody decided to take it.

Pick up one thing today that is not your fault, and do not mention it afterward. Notice that the room you are standing in is partly whatever you decide to make it. The habit costs about four seconds.
