Writing a book will quiet the inner voices.

Just published my first eBook on Amazon.

Don't care if I sell a single copy. I can sleep now.

I've written a few others, but didn't publish.

I have tons of content stored. My take on your advice is that writing is an absolute necessity for maintaining balance of mind. Proofreading becomes a process for validation. But separate writing from publishing. Write every day. Publish when and if you've come up with something to publish.
