A quote
There is the same difference between winning a new friend and having already won him, as there is between the farmer who sows and the farmer who reaps. The philosopher Attalus used to say: “It is more pleasant to make than to keep a friend, as it is more pleasant to the artist to paint than to have finished painting.
