“Whenever you want to cheer yourself up, consider the good qualities of your companions, for example, the energy of one, the modesty of another, the generosity of yet another, and some other quality of another; for nothing cheers the heart as much as the images of excellence reflected in the character of our companions, all brought before us as fully as possible. Therefore, keep these images ready at hand.”
― Marcus Aurelius, Meditations
