What should I do if I have a phenomenal fantasy book/story idea? I have the plot and idea, but have average writing skills and no resources.

Write the story. Then rewrite it. Then rewrite it again— and again— and again until it’s not average, it’s fantastic.

Most writers aren’t geniuses. They are people like yourself who have average skills. What makes them good writers is the effort they are willing to put into the process to make their stories the best that they can.

I believe there’s a saying that’s pretty much spot-on: Genius is one percent inspiration and ninety-nine percent perspiration.
