Then unrelated ideas seep into our writing. Before long we’re mired in a verbal bog and can’t get ourselves out.
What are we to do about it?
First, start with a good idea that you’ve looked at from all angles. If you can't write it down, you haven't thought it out.
Second, when you begin writing stick to your idea. Don’t allow stray thoughts and information — no matter how tempting — to intervene.
Third, remind yourself to say one thing, and one thing only.
If you stick to a single idea, your writing will be stronger, whether you’re writing a query, a sales letter, a memo, a speech, a personal note, or even that how-to book you plan to write one of these days.
Keep asking yourself: “What is my main idea?”
In business writing, the main thing is keeping the main thing the main thing.
