I know I'm late posting this for Friday, but it's just NOW I had this idea, so here we go...
I was emailing with a fellow author and the topic of something being the next big thing came up. In my reply to her I said that because readers are all different (and of course, the publishing world often changes) for all we know "French speaking Leprechauns who dance ballet could make readers nuts" over the story.
A lot of big name authors say in interviews "I never expected this to happen." How could they? You write a story and get into it, you fix it up. Sometimes people get excited, sometimes they don't. You just never know.
I mean it could happen that purple aliens who wear high-top shoes (or rather, chucks) and parachute pants would make people rush out and buy every single book in the series.
Or maybe it would be a cop who does miming in the park on Saturdays.
The wonderful thing about books and writing is that as long as you tell a good story that draws a reader in, there's all kinds of ideas a person can play with and write about.
The fact of the matter is, you won't know if you don't try. This is something I've said to myself (more than once). If you don't try to be professional and work at this and actually put yourself out there you won't ever know for sure.
True, you might not make it; you might have to use a different story, and even if you're not the next BIG thing, you could be the next good-enough-for-sales-and-a-good-amount-of-readers-love-your-story thing.
Like so many authors have already said: don't give up.
Keep honing your skill, keep learning, keep growing.
Have A Great Weekend!
