“Forget everything else. Keep hold of this alone and remember it: Each of us lives only now, this brief instant. The rest has been lived already, or is impossible to see. The span we live is small – small as the corner of the earth in which we live it. Small as even the greatest renown, passed from mouth to mouth by short-lived stick figures, ignorant alike of themselves and those long dead.”
-Marcus Aurelius, Meditations, Book Three: In Carnuntum
