Good writing uses the paragraph as the unit of composition. Many writing problems occur because the writer has a faulty concept of the paragraph. Good writing uses definite, specific concrete language. But we rarely use that phrase in that context anymore. The usage of deals with is so widespread and indefinite that it conveys no clear meaning at all.
Good writing omits all unnecessary words.
Never make the vehicle bigger than the idea. Good writing uses a variety of sentence structures and lengths. Repetition is boring whether its ideas, words or structures. Don't bore the audience with sameness. Good writing relies on nouns and verbs.
