Writing is a conversation between you and your reader.
In your face-to-face conversations, at work and in your personal life, you strive to use clear and engaging language. Similar rules apply to good writing.
Many professionals write in a formal, puffed-up style (as per your request, hereinafter, I am of the opinion…) because they think it will make their work appear more important and impressive.
The opposite is true, of course, as you know if you’ve ever read a memo or report written loaded with this type of gobbledegook. Pompous writing like this confuses and frustrates readers. Worse, it gives the impression that the writer either doesn’t think clearly or doesn’t respect readers’ time. Or both.
Strive to write your work-related documents in a conversational, informal style that’s easy to understand. This actually will impress your readers.
