The Importance of Sleep

You talk about this idea of being non-instrumental with How We Use Our Time. What does that mean? I think doing nothing is obviously not doing actually nothing, but it looks like nothing from the point of view of productivity or even the idea of having something to show for your time. Things like listening or observing or even taking care of yourself, these are activities that don't really seem to go anywhere. They don't really have deliverables, so to speak.
