You are a good storyteller. With every book you've written, you've gotten better. And your passion is based on the certainty that you are good at writing. That makes you learn everything you need to promote your gift: typing, publishing on amazon, creating physical and digital books. Even advertising in stores and markets.
Same thing happened to me, I went to typing class for 3 years when I was young. I hated it. But my gift urged me to do it, as well as to learn how to use the technological tools (which bore me a lot :-) to keep making it easier for my gift to reach more people, as in your case.
A hug, my friend.
