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

Vigorous writing is concise.

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

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.

The approach to style is by way of plainness, simplicity, orderliness, sincerity.

Never call a stomach a tummy without good reason.

Rewrite and revise. Do not be afraid to seize what you have and cut it to ribbons ... Good writing means good revising.
