To 'know your place' is a good idea in politics. That is not to say 'stay in your place' or 'hang on to your place', because ambition or boredom may dictate upward or downward mobility, but a sense of place - a feel for one's own position in the control room-is useful in gauging what you should try to do.
William SafireDo 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. De-accession euphemisms. If any word is improper at the end of a sentence, a linking verb is. Avoid trendy locutions that sound flaky. Last, but not least, avoid cliches like the plague.
