In the quiet hours when we are alone and there is nobody to tell us what fine fellows we are, we come sometimes upon a moment in which we wonder, not how much money we are earning, nor how famous we have become, but what good we are doing.
A. A. MilneThe old grey donkey, Eeyore stood by himself in a thistly corner of the Forest, his front feet well apart, his head on one side, and thought about things. Sometimes he thought sadly to himself, "Why?" and sometimes he thought, "Wherefore?" and sometimes he thought, "Inasmuch as which?" and sometimes he didn't quite know what he was thinking about.
