"Do not put statements in the negative form. And don't start sentences with a conjunction. If you reread your work, you will find on rereading that a great deal of repetition can be avoided by rereading and editing. Never use a long word when a diminutive one will do. Unqualified superlatives are the worst of all. Last, but not least, avoid cliches like the plague."
