Pablo Picasso was sketching in a park one day when a woman recognized him and asked if he'd sketch a portrait of her. He tooka few seconds to look at her before putting his pen to the paper. In a few strokes, he was done. She was thrilled when she saw the sketch, and then she asked him how much she owed him.

“5,000 francs, madam,” replied Picasso.

“5,000? But it only took you a minute!”

Picasso replied, “No, madam. That took me my entire life.”
