I ran across the following quote in my files today. It’s an important reminder–short, sweet and well-spoken. Follow this advice for clear and concise business writing: Keep sentences and paragraphs short. Give sentences the “breath test” by reading them aloud. If you run out of breath before you get to the end of the sentence, it’s too long and should be broken into two or more sentences.
