My commodity as a writer, whatever I'm writing about, is me. And your commodity is you. Don't alter your voice to fit the subject. Develop one voice that readers will recognize when they hear it on the page, a voice that's enjoyable not only in its musical line but in its avoidance of sounds that would cheapen its tone: breeziness and condescension and clichรฉs.
William ZinsserNobody told all the new e-mail writers that the essence of writing is rewriting. Just because they are writing with ease and enjoyment doesn't mean they are writing well.
William ZinsserKeep your paragraphs short. Writing is visual - it catches the eye before it has a chance to catch the brain.
William ZinsserNever hesitate to imitate another writer. Imitation is part of the creative process for anyone learning an art or a craft. Bach and Picasso didn't spring full-blown as Bach or Picasso; they needed models. This is especially true of writing.
William ZinsserWriters who think THEY are being criticized when only that writing is being criticized are beyond a teacher's reach. Writing can only be learned when a writer coldly separates himself from what he has written and looks at it with the objectivity of a plumber examining a newly piped bathroom to see if he got all the joints tight.
