There is a difference between going to sleep with everything accomplished and going to sleep having done all one can do. In the former, the to-do list is empty. In the latter, the to-do list remains. There is nothing quite like sleep when one is free from the to-do list—such a sense of freedom. There is nothing quite like freedom when much remains to do—such a sense of challenge.
And what about going to sleep when one has not much bothered with the to-do list? I don’t know if that behavior is the “art” of ignoring or just an act of ignorance.
