Well, while I'm writing another novel, thoughts about self-publishing have come to mind. I found an article by Peter Bowerman called 8 Mistakes Self-Publishers Make And How to Avoid Them! I found this article very helpful and I copied some of the main points below.
Mistake #1. You wrote an unnecessary book (this is especially true for non-fiction), but when writing the book you need to make sure there's a market for it.
Mistake # 2. You have a bad book cover - you may want to hire a graphic artist, and not one from your printer place
Mistake # 3. Your title is lame - pretty self-explanatory
Mistake # 4. You didn’t hire an editor and a proofreader - it's extremely important to find someone to look over your book that isn't related to you.
Mistake # 5. You think small (Part One) - don't just celebrate any validation (getting minor publicity) you deserve to be there.
Mistake # 6. You promote the old-fashioned way - Go through the Internet and target your audience and promote, promote, promote.
Mistake # 7. You think small (Part Two) - Sending out a few dozen review copies isn't enough. Think big and send out 350-400 copies (just an example.)
Mistake # 8. You forgot that you have just ONE job - you may want to hire someone to help you promote.
