Every child makes up stories and draws pictures and, in the beginning, they do so unselfconsciously.
It's simply part of being a young human delighting in the world. However, at some point most people give up art and storytelling and move on to other interests. People who write are curious about a lot of things, disparate things, and feel compelled to record their ideas. They can be interrupted, but they can't be stopped. All authors can be teachers, both for what to do and what not to do.
