Proofread your writing to see if any words out and to avoid misteaks. Remember to never split an infinitive. Take the bull by the hand, and avoid mixing metaphors. The adverb always follows the verb. The passive voice is to be avoided.
Understatement is absolutely, positively best.
Unqualified superlatives are the worst of all. Verbs has to agree with their subject. Writing carefully, dangling participles must be avoided. Last, but not least, avoid cliche's like the plague.
