Editing is all about trying to see the story that’s on the page, not the story in your head. You can attain greater objectivity by changing the font or not looking at your story for a few weeks, but when it comes to the actual changing of the words, there’s another trap many writers fall into. The trap is that you’ll simply skim through your chapters, changing maybe one word a page, and reach the end feeling like you’ve accomplished something. In reality, you’ve probably made your story only slightly better. As busy writers, slightly better isn’t a great result for the amount of time you’ve used.
Fear not! There is a better way: Instead of editing the way you read, edit backwards.
