Back on Track

I'm up to over 4000 word on my Sheppard H/C story, and though the going is slow so far it's been cooperating a lot better than what I was previously writing. Unfortunately it's still not the kind of story that writes itself. I don't get many words down before I have to stop, step back, and detail what happens next in my mind. When a story "writes itself" what happens next usually comes pretty quick to me - within minutes, sometimes even seconds. With my current story, I need about an hour, sometimes even a day.

It's weird how easy some stories are to write while other stories are like herding cats. Is it motivation that makes the difference? The type of story it is? The content? I wish I knew. My amnesia story, plus another story I'm writing, have been so incredibly cooperative they're like cutting warm butter. But I have no idea what it is about those stories that make them so much easier to write.
