Any attempt at fiction for me always started with what sounded like a good story idea, followed by a lot of pointless and tedious flapping about trying to flesh things out, and terminating with frustration and disappointment.
But setting out to write stories for EA has cured me of the "I can't write me no fiction blues"! While the "end" of these stories presents a pretty large target, it is at least a target. Something I've not had just winging it with fiction. And the target keeps me going and I actually finish my stories. They don't (most of them) ever make it to EA though.
When I'm done, I sanitize and abstract the story till it becomes a main stream short story - something you would let your 13 year old niece read. The result was my first sale of a fiction work! It started out as a story for EA about a spy who gets captured. You can guess how that originally turned out.
The sanitized version was accepted for publication. Not by a mainstream publication. In fact, this outfit pays in copies instead of cash. But its a start!
I am Zooooooo 'appy!
