William Safire's Rules for Writers: Remember to never split an infinitive.

William Safire's Rules for Writers:

Remember to never split an infinitive. The passive voice should never
be used. Do not put statements in the negative form. Verbs have to
agree with their subjects. Proofread carefully to see if you words
out. If you reread your work, you can find on rereading a great deal
of repetition can be avoided by rereading and editing. A writer must
not shift your point of view. And don't start a sentence with a
conjunction. (Remember, too, a preposition is a terrible word to end a
sentence with.) Don't overuse exclamation marks!! Place pronouns as
close as possible, especially in long sentences, as of 10 or more
words, to their antecedents. Writing carefully, dangling participles
must be avoided. If any word is improper at the end of a sentence, a
linking verb is. Take the bull by the hand and avoid mixing
metaphors. Avoid trendy locutions that sound flaky. Everyone should
be careful to use a singular pronoun with singular nouns in their
writing. Always pick on the correct idiom. The adverb always follows
the verb. Last but not least, avoid cliches like the plague; seek
viable alternatives.
