If you are pained by any external thing, it is not this that disturbs you, but your own judgment about it.
Marcus AureliusForward, as occasion offers. Never look round to see whether any shall note it.... Be satisfied with success in even the smallest matter, and think that even such a result is no trifle.
Marcus AureliusAre you distracted by outward cares? Then allow yourself a space of quiet wherein you can add to your knowledge of the Good and learn to curb your restlessness. Nowhere can a man find a quieter or more untroubled retreat than in his own soul. Avail yourself often, then, of this retirement, and so continually renew yourself.
Marcus Aurelius
