“Vigorous writing is concise.”

“Vigorous writing is concise. A sentence should contain no unnecessary words, a paragraph no unnecessay 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 subjects only in outline, but that every word tell.”

“Consciously or unconsciously, the reader is dissatisfied with being told only what is not; the reader wishes to be told what is... If your every sentence admits a doubt, your writing will lack authority.”

“When a sentence is made stronger, it usually becomes shorter. Thus, brevity is a by-product of vigor.”

“1. Make the paragraph the unit of composition: one paragraph to each topic.”

“Omit needless words.”

“It's worse to irresolute than wrong.”
