"Appealing to readers is the endgame. They want story over prose, so concentrate on that (aim for both, but concentrate on story)."
By Dennis Lowery
In the article Hugh talks about building a body of good work (stories that are appealing to readers) and how critical that is to discovery of your stories and building a successful career as a writer and author. I agree with him. Writing only one book... one story will not lead to a sustainable and successful career as a writer.
You have to keep creating good stories.
You have to understand writing (if you want to make a living from it) is a business and you need to study, learn and apply successful business and professional writer practices to give you a foundation to build on and operate from. And you have to take what you've learned and concentrate on connecting directly with your readers.
I work on that every day... because it will pay off not only for my writing and my books... but because it will also bring visibilty (and discoverability) to books I help clients write.
One last bit of advice: Focus more on writing your next book or story and on reaching readers and less on fixating about agents and publishers.
