If you are pained by external things, it is not they that disturb you, but your own judgement of them. And it is in your power to wipe out that judgement now.
Marcus AureliusBecause a thing seems difficult for you, do not think it impossible for anyone to accomplish.
Marcus AureliusLook within, for within is the wellspring of virtue, which will not cease flowing, if you cease not from digging.
Marcus Aurelius... Allow yourself a space of quiet, wherein you can add to your knowledge of the Good and learn to curb your restlessness. Guard also against another kind of error: the folly of those who weary their days in much business, but lack any aim on which their whole effort, nay, their whole thought, is focused.
Marcus Aurelius
