To air one's views gratuitously, is to imply that the demand for them is brisk.

Rich, ornate prose is hard to digest, generally unwholesome, and sometimes nauseating.

Every writer, by the way he uses the language, reveals something of his spirit, his habits, his capacities, his bias....Avoid the elaborate, the pretentious, the coy, and the cute. Do not be tempted by a twenty-dollar word when there is a ten-center handy, ready and able.

None are so fallible as those who are sure they're right.

Make definite assertions. Avoid tame, colorless, hesitating, non-committal language.

It is worse to be irresolute than to be wrong.

If you use a colloquialism or a slang word or phrase, simply use it; do not draw attention to it by enclosing it in quotation marks. To do so is to put on airs, as though you were inviting the reader to join you in a select society of those who know better.
