I've created a whiteboard to deal with common issues and problems associated with fiction writing, book publishing, book marketing and author business. The title is What's the problem?
It isn't quite finished yet, but there is a lot of useful material on it. Actually, it may never be finished since I'll keep adding more information to it over time.
You can access the whiteboard using this link: https://app.scrintal.com/app/board/az6bz3r572jpqa4zad3e08ened
Scroll around and bookmark it for future reference.
My website hankquense.online also has a lot of problem-solving material.
