The true joy of humankind is in doing that which is most proper to our nature; and the first property of people is to be kindly affected towards them that are of one kind with ourselves.
Marcus AureliusBecause a thing is difficult for you, do not therefore suppose it to be beyond mortal power. On the contrary, if anything is possible and proper for man to do, assume that it must fall within your own capacity.
Marcus Aurelius
