Is it possible for a complete noob to get into fictional writing and become good at it?
It's possible. I think you can become good at it with practice. The community that you subscribed have daily and even weekly prompt that you can try. I participated in the past but because lack of time, I didn't do them anymore.
Thanks so much for the warm welcome. And thanks for answering one of the questions I was curious about. I hope to learn anf improve that aspect of my writing.
