Remember: Matter: how tiny your share of it. Time: how brief and fleeting your allotment of it. Fate: how small a role you play in it.
Marcus AureliusHow powerful is man! He is able to do all that God wishes him to do. He is able to accept all that God sends upon him.
Marcus AureliusHow easy it is to repel and release every impression which is troublesome and immediately to be tranquil.
Marcus AureliusRemember how often you have postponed minding your interest, and let slip those opportunities the gods have given you. It is now high time to consider what sort of world you are part of, and from what kind of governor of it you are descended; that you have a set period assigned you to act in, and unless you improve it to brighten and compose your thoughts, it will quickly run off with you, and be lost beyond recovery.
Marcus Aurelius
