It sounds like an absurd question, but many writers–especially people who write in business settings—almost never use them.
In this case, of course, we’re speaking metaphorically rather than literally. As American novelist, short story writer, screenwriter, playwright, and actor Truman Capote said in an interview, “I’m all for the scissors. I believe more in the scissors than I do in the pencil.”
It’s as important for business writers as it is for novelists: first get all your thoughts on paper (or on your computer screen), then come back and take a scalpel to what you’ve written. Be merciless. If it’s clunky, or unclear, or dull, or wordy, you must get rid of it.
That’s one reason you may be thinking of hiring a professional editor—one who is sensitive to the rhythm and power of words, and can take your writing and make it something that is compelling rather than confusing or lackluster. May I be of service?
