As long as a film stays unmade, the book is entirely yours, it belongs to the writer. As soon as you make it into a film, suddenly more people see it than have ever read the book.

People were always sorry. Sorry they had done what they had done, sorry they were doing what they were doing, sorry they were going to do what they were going to do; but they still did whatever it is. The sorrow never stopped them; it just made them feel better. And so the sorrow never stopped.

Writing is like everything else: the more you do it the better you get. Don't try to perfect as you go along, just get to the end of the damn thing. Accept imperfections.
