This is the chief thing: be not perturbed, for all things are according to the nature of the universal.
Marcus AureliusTo no man make yourself a boon companion: Your joy will be less but less will be your grief
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 AureliusWhen forced, as it seems, by your environment to be utterly disquieted, return with all speed into your self, staying in discord no longer than you must. By constant recurrence to the harmony, you will gain more command over it.
Marcus AureliusDoctors keep their scalpels and other instruments handy, for emergencies. Keep your philosophy ready too - ready to understand heaven and earth. In everything you do, even the smallest thing, remember the chain that links them. Nothing earthly succeeds by ignoring heaven, nothing heavenly by ignoring earth.
Marcus Aurelius
