I like this story about the artist Pablo Picasso. Late in life, when Picasso was very famous, he had gone back to visit the studio he had as a struggling young artist in Paris. Outside the studio, sleeping on a bench, he recognized an old tramp he had known in those early days. The man had fallen on hard times.
Picasso went over to a rubbish bin, found a crumpled piece of paper, smoothed it out, and did a beautiful sketch on it. Signing it, he handed it to the tramp and said, “Here, buy yourself a house.”
