I was reading Kate Elliot's blog I Make Up Worlds today, and came across some comforting advice to remember when I doubt whether anyone will want to read my stories. She has a very interesting blog generally, which is well worth reading. She said:
"You don't know how your creative work will be recieved. All you can do is offer up what is present in your imagination."
So all I can do is make the story as good as I can. After I've done the best I can with the story I have to tell, the only thing I can do is launch it on the world. If other people like it, that's brilliant, but the important thing is that I created something I'm happy with.
