if burn out: add more fuel Oxygen + solid matter. What is oxygen? Rejuvinating: maybe vacation, maybe relax more in the work day. What is solid? The "why", though I don't think I quite got the phrasing. Seems too easy just to have direction and motivation- although, what else could it be? In not too old medical books, they often referred to a man's "fire" as part of his overall well being. His hearth and happiness, et cetera. In some sense his gall; or gaul: how he carries fire... or his gall bladder?
