“It's worse to irresolute than wrong.”

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

“Omit needless words.”

“Vigorous writing is concise.”

“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.”

“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.”

“None are so fallible as those who are sure they're right.”
