Figure Out What Is Missing From Being A Book Writer To A Book Seller
You need to be active on social media. Not only writing the daily quip about dinner plans, favorite movie lines (Forrest Gump's line, "That's My Boat" as it crashes into the dock), sports score, or politics, you need to be talking about your book(s) and product(s). _
Actively making videos is definitely difficult. What to do, what not to do, it's exhausting and discouraging, but we've got you covered (even if you want a faceless video).

People want to know about your book(s) and product(s). Start gathering email addresses and tell people about your book (that's why they signed up anyway).
Just like the videos and the emails, have a website with a purpose. Turn your website into a store to sell your book(s) and product(s)
The reason that your book isn't selling isn't about the quality or value of your work. The reason is because people don't know about it. The missing piece is getting yourself and your book(s)/ product(s) into the right places. Get the help that you need.
