There’s a famous story about Picasso.
He’s sitting in a café in Paris.
Someone recognizes him and asks for a quick drawing.
Picasso takes a napkin, sketches something in one fluid motion—
and slides it over.

“That will be five hundred francs.”
“But… it took you less than a minute?”
“Indeed,” Picasso replies.
“But it took me forty years to be able to draw it in one minute.”

Whether it really happened is less interesting.
