I take joy in the merely real, because I learned to; I take joy in seeing a vastly improbable coincidence where there is none, because of a hiccup of evolutionary psychology. The first is motivating, the second is blinding, but before I deconstruct the second (and perhaps build the first from its parts), I can take it in, short-term. There's no reason not to stop for a moment and feel the joy/marvel/amazement that you suspect you're feeling for a stupid reason; just don't let your guard down.
