“Vigorous writing is concise. A sentence should contain no unnecessary words, a paragraph no unnecessary sentences, for the same reason that a drawing should have no unnecessary lines and a machine no unnecessary parts. This requires not that the writer make all sentences short, or avoid all detail and treat his subject only in outline, but that every word tell.”
–William Strunk, Jr.
Note: The use of “tell” here is quite different than what we mean by “show, don’t tell” — which hopefully is clear and makes sense to you. If not, please ask away — the comments are open!!
