Every system eventually reveals what its repeated inputs produce.

Feed anything the same thing long enough and it will show you what that produces. This is true of a company, a household, a friendship, and a body. The output is not a judgment or a surprise, it is a summary of the inputs, delivered patiently and on its own schedule.

Name what you are putting into something regularly, including the parts you would rather not count. Then ask whether the result you are seeing is a fair reflection. Usually it is, and that makes the change straightforward if not easy.
