I'm going to make this somewhat short and sweet: Only you should see the first draft of your manuscript. Please, please, please do not submit your first draft to publishers, agents, and never self-publish it for the public to see! Do your career a huge favor and at least self-edit and revise before you submit your manuscript anywhere. If you plan to self-publish, hire a professional editor before it sees the light of day. I understand that paying a qualified editor is quite expensive, but your book (and career) is worth the investment. I promise you that the majority of the most successful authors in the world do not turn in their first draft. It's simply not a smart career move.
I swear I'm not one of the Quality Police. Really, I'm not. I just wouldn't want anyone claiming that you've produced "bad literature." Don't give the Quality Police any more fuel!
Have you ever read a book that appeared to be a first draft? Comment.
