[F. Scott Fitzgerald] had told me at the Closerie des Lilas how he wrote what he thought were good stories and which really were good stories for the Post, and then changed them for submission, knowing exactly how he must make the twists that made them into salable magazine stories. I had been shocked at this and I said I thought it was whoring. He said it was whoring but that he had to do it as he made his money from the magazines to have money ahead to write decent books. I said that I did not believe anyone could write any way except the very best he could write without destroying his talent. Since he wrote the real story first, he said, the destruction and changing of it that he did at the end did him no harm. I could not believe this and I wanted to argue him out of it but I needed a novel to back up my faith and to show him and convince him, and I had not yet written any such novel.
