Short Stories, or "How do you tell your muse to shut up?"

Seriously! I have a few ideas I'm kicking around that would make neat stories, but as you've seen with Becoming Robin when the creative juices start flowing they Do. Not. Stop.

I've had authors here tell me they wish they could write novel-length works, but I have the exact opposite problem, in that I can't sit down and write a short story. I'm a sucker for detail and drawn-out plots, extensive narration and dialogue.

Am I a lost cause? Should I just stick to writing angsty coming-of-age drama? ;-)

Just kidding about that last part, but I would welcome any advice on future writing to ah... "tone it down", shall we say :-D
