One day, Picasso is sitting in a restaurant. A woman approaches him with a table napkin. She asks him to draw something on the paper serviette. Within thirty seconds he makes her a drawing.
'That'll be 10,000 dollar' he says.
'Ten thousand dollars? For only thirty seconds of work?' the woman asks.
'Yes, but it took me more than 40 years to get where I am' Picasso answered.
