so many writers get obsessed over their first book, spending years writing, editing and polishing it without moving on to the next one. We all have self-doubt, we all suffer from fear of failure, fear of judgment. That never stops, even for the most experienced writers from what I've heard. The best thing to do is to write that book, then another, then another, then another. Work with a professional editor on every book and learn from the experience. You will improve every time.
