I told someone in a writer's group once,"I can't read these chapters out loud yet. I'm not finished with them."
And they said,"You're supposed to share it with people and editors BEFORE you finish."
I disagree entirely. You share after you're done. If you can still find stuff wrong with your manuscript, then you're not ready for an editor. You're only ready once you think it's perfect. That way, they're pointing out stuff you'd never find on your own and you learn and grow as an author.
