With a novel, which takes perhaps years to write, the author is not the same man he was at the end of the book as he was at the beginning. It is not only that his characters have developed—he has developed with them, and this nearly always gives a sense of roughness to the work: a novel can seldom have the sense of perfection which you find in Chekhov’s story, ‘The Lady with the Dog.’

Graham Greene (via writingquotes)
