Anything maintained is quietly resisting decay.

Anything that continues to work, a house, a body, a friendship, a piece of software, is being actively held against a constant pull toward decline. The stability is not natural; it is the product of unglamorous effort that mostly goes unnoticed because success looks like nothing happening. Once the effort stops, the decline resumes immediately and quietly.

Make a list of what you depend on that requires upkeep, including relationships. Ask which of them nobody is currently maintaining. That question tends to identify the next thing to break.
