William Goldman gave a great interview in which he talks about how little talent he had as a young writer trying to sell short stories. He was rejected countless times and had to take other kinds of work along the way, but his persistence paid off when he started writing scripts and became one of Hollywood’s most successful screenwriters of all time. He is the creative force behind such films as The Princess Bride, Maverick, Heat, and Butch Cassidy and the Sundance Kid.
Nobody knows anything.
Understand this: all the sleaze you’ve heard about Hollywood? All the illiterate scumbags who scuttle down the corridors of power? They are there, all right, and worse than you can imagine.
