When I'm writing, I always doubt that I can fill one page much less the thirteen through twenty that constitute a chapter. Even when I know what's going to happen, I doubt that the pages will be enough, especially since I am a short writer to begin with (And that has nothing to do with height). And then I start writing. Basically I'm just describing the pictures in my head and transcribing the dialogue I hear there. Not that it's a smooth and easy process. Sometimes the "film" breaks, or the projectionist takes a break, or the film is fed into the machine (Yes, this is old fashioned stuff here--no DVD's) wrong so the film isn't clear or runs ratchety. But the chapter grows and I am always amazed by how much I get on paper. Soon I worry that I'm going to overrun the chapter by five or six pages, because there's always so much more to tell. But eventually it always works out and my chapter is complete and the right length.
I call this the Magic. The story keeps playing in my head and all I have to do is get it on paper. Or computer if we're trying to modernize the process here.
Books I'm reading now:
The Big Bad Wolf by James Patterson
Fast and Loose by Elizabeth Bevarly
