A woman approached Picasso in a restaurant and asked him to scribble something on a napkin for her. She said she would be happy to pay whatever he felt it was worth. Picasso quickly sketched a beautiful piece that wowed the people watching.

Then he said, “That will be $10,000.”

“But you did that in thirty seconds,” the astonished woman replied. “No,” Picasso said. “It took me forty years to be able to do that.”
