Have you ever been stuck with a writing project and given it to a friend or colleague to read?
When you do that, you were trying to look at your writing through the eyes of your readers.
This need to look out for readers is also what keeps most professional editors in business. An editor provides an experienced second set of eyes for what you have written.
Besides hiring an editor, there are concrete steps you can take to lead your readers through your points in a way that makes them comfortable and not frustrated.
