30 seconds

From an article by a professional screenwriter about hating it when random people ask him to read their scripts:

There's a great story about Pablo Picasso. Some guy told Picasso he'd pay him to draw a picture on a napkin. Picasso whipped out a pen and banged out a sketch, handed it to the guy, and said, "One million dollars, please."

"A million dollars?" the guy exclaimed. "That only took you thirty seconds!"

"Yes," said Picasso. "But it took me fifty years to learn how to draw that in thirty seconds."
