The philosopher Attalus used to say: “It is more pleasant to make a friend than to have one, as it is more pleasant to the artist to paint than to have painted.” When one is busy and absorbed in one’s work, the very absorption affords great delight; but when one has withdrawn one’s hand from the completed masterpiece, the pleasure is not so keen. Now it is the fruit of his art that he enjoys; it was the art itself that he enjoyed while he was painting. Seneca, Epistles 9.7
