It's interesting when you write exactly what you want and tell yourself you don't give a care in the world to what people will think of it or YOU for writing it. Of course, it's one thing if you decide to stick that project in the drawer at the end of the day...quite another thing if you decide to publish the thing.
Let's face it. Writing fiction is not only difficult in all the technical aspects, but it is difficult emotionally as well. You really DO care about what people think. You're putting your creativity out there to be scrutinized and critiqued, ignored and praised. Most of the time conflicting emotions abound.
When I published my novella, Cinders, I expected many readers to dislike the ending, and they do. I received two extremely honest reviews this morning. Both reviewers disliked parts of the book and on average gave it 3 stars. Still, they praised the writing and other things about the book they liked.
Like I said, I expected this kind of reaction, but it hurts anyway - no matter what you expect - when someone you like and respect doesn't fawn over your book like you envisioned them doing. I've had this happen again and again and again with my writing, published and not published. I've also had some readers love my work when I thought they'd hate it. Go figure!
All this is just to say, once again, that you should write what is closest and most real for you and no one else. You should also keep a very open mind about feedback, critiques, and reviews. I have learned to embrace every opinion and celebrate the fact that people read my work in the first place!
What is hardest for you to embrace about sharing your work?
