Small messes don’t stay small. They invite friends.

Disorder is self-reinforcing, because a space that is already untidy removes the reason to be careful with the next thing. One dish becomes a sink, one unread message becomes an inbox, one skipped day becomes a pattern. The first item is not the problem, the permission it grants is.

Reset one small area completely rather than improving several a little. Then protect that one area, since a clean surface tends to defend itself. Handling the first item immediately is much cheaper than handling the twentieth.
