At daybreak, when you loathe the idea of having to leave your bed, have this thought ready in your mind: I am rising for the work of man." Should I have misgivings about doing that for which I was born, and for the sake of which I came into this world? Is this the grand purpose of my existence-to lie here snug and warm underneath my blanket? Certainly it feels more pleasant. Was it for pleasure that you were made, and not for work, nor for effort? Look at the plants, sparrows, ants, spiders, and bees, all working busily away, each doing its part in welding an orderly Universe. So who are you to go against the bidding of Nature? Who are you to refuse man his share of the work? To live each day as though it were your last-never flustered, never lazy, never a false word-herein lies the perfection of character.

(Marcus Aurelius)
