The rabbit said to the hare: “Hey there, you’re always doing nothing and sleeping. Are you doing that in order to appear contemplative?” “And you,” the hare said, “are you doing nothing by always working?” The rabbit replied, “As long as both of us, therefore, wish to appear to have little leisure, we follow our natures. It would be very hard for you to do as I do, and for me to do as you do.”

Leon Battista Alberti, Fables
