Thought that Hemingway’s philosophy for writing might be interesting, but it’s not.
This article about his Fight-Club-alike rules includes the following gem, which I hope is tongue in cheek but suspect is not:

If you have taken the time to learn to write beautiful, rock-firm sentences, if you have mastered evocation of the vivid and continuous dream, if you are generous enough in your personal character to treat imaginary characters and readers fairly, if you have held on to your childhood virtues and have not settled for literary standards much lower than those of the fiction you admire, then the novel you write will eventually be, after the necessary labor of repeated revision, a novel to be proud of, one that almost certainly someone, sooner or later, will be glad to publish.
