“I write fast because I have not the brains to write slow.”

His name was Georges Simenon. He’s best known for two
things. He wrote a series of 75 Inspector Maigret novels featuring Paris police
superintendent Jules Maigret. And he wrote each his novels very quickly: usually
in about a week and a half.
He was born in Liege, Belgium and quit school when he was
15. He published his first novel at 18, and in the next seven years wrote more
than 150 novels and novellas. Over a career of 50 years, he wrote some 500
novels.
In a recent article in the New Yorker, Joan Acocella describes his writing practice: “Every
morning, he sat down and completed his self-assigned daily quota of eighty
typewritten pages. Then he would vomit, from the tension, and spend the rest of
the afternoon relaxing.”
