Well, there are several reasons: 1) Technically, I know various writing styles real well (AP, GPO, Chicago, APA). 2) Through my years of journalism and other writing experience, I've developed a knack for clear, accurate, succinct expression and finding just the right words for a certain thought. 3) I was trained in Biochemistry in college. This developed my strong analytical ability, which helps me produce clear, logical, and error-free copy. 4) I write poetry, so I bring an aesthetic sensibility to the written word, helping me produce writing that's tasteful, sensitive, and moving. 5) I have a broad general knowledge, in everything from world history to science, art to gastronomy, which strengthens my fact-checking and editing in many ways.
