Remember 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 AureliusWhen jarred, unavoidably, by circumstance revert at once to yourself and don't lose the rhythm more than you can help. You'll have a better grasp of harmony if you keep going back to it.
Marcus AureliusLook within. Within is the fountain of good, and it will ever bubble up, if thou wilt ever dig.
Marcus AureliusA 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 Aurelius
