Making a living as an author…

If you are serious, and you want to make a living as an author, then you need to hustle. Period. If you can’t make that quality, then you need to concentrate on your craft and practice more.
One other thing, quality comes with practice. If you are prolific, then you become a better writer because you are writing. The more you do anything the better at it you will become. So in a way, quantity does add to quality.
