A noble man compares and estimates himself by an idea which is higher than himself; and a mean man, by one lower than himself. The one produces aspiration; the other ambition, which is the way in which a vulgar man aspires.
Marcus AureliusDiscard everything except these few truths: we can live only in the present moment, in this brief now; all the rest of our life is dead and buried or shrouded in uncertainty. Short is the life we lead, and small our patch of earth.
Marcus Aurelius
