Opening the book…
Most of what keeps a life running is dull and invisible. The backups, the dentist, the slow reply you owe, the thing you keep meaning to fix. Neglect is quiet right up until it isn't. I have noticed that the small undone tasks don't disappear; they gather interest and arrive later as a crisis. Boring maintenance is how you buy calm.
I keep a short list of the unglamorous things and do one or two each week, before they become urgent. I try to treat the ten-minute fix as worth doing now rather than dreading for a month. Friday afternoons, when I am too tired to create, are good for this kind of tidying.
Not everything needs maintaining. Some things you are keeping alive out of habit, not need. Before you fix it again, ask whether it is worth keeping at all.
