by C. S. Lewis
1. Turn off the radio.
2. Read good books and avoid most magazines.
3. Write with the ear, not the eye. Make every sentence sound good.
4. Write only about things that interest you. If you have no interests, you will never be a writer.
5. Be clear. Remember that readers can't know your mind. Don't forget to tell them exactly what they need to know to understand you.
6. Save odds and ends of writing attempts, because you may be able to use them later.
7. You need a well-trained sense of word-rhythm, and the noise of a typewriter will interfere.
8. Know the meaning of every word you use.
9. Don't use words too big for the subject. Don't say "infinitely" when you mean "very"; otherwise you'll have no word left when you want to talk about something really infinite.
10. Even in literature and art, no man who bothers about originality will ever be original: whereas if you simply try to tell the truth (without caring twopence how often it has been told before) you will, nine times out of ten, become original without ever having noticed it.
