Your standards travel with you. A sloppy habit at home shows up at work by Wednesday.

Habits do not stay in the room where you formed them. The way you leave your own kitchen is the way your hands want to leave a work surface, because nobody has two separate selves, one careless and one careful. What you practise at home is what will be available under pressure. That is unsettling and also useful, since it means ordinary chores are training.

Choose one habit at home you have been letting slide and tighten it: the bed, the sink, the bag by the door. Keep it for a week and watch whether anything at school or work moves with it.
