I labored through five pages tonight, written with my favorite mechanical pencil on loose blue paper. To be honest, I wasn't in the mood for writing when I sat down at my desk.
Sometimes it takes pushing beyond that inertia to get things moving. Once I was started, it moved along quite well. There were a few times when I couldn't write fast enough to keep up with the outpouring storyline.
Started trying out a technique I read about a few months ago. Write until it gets really hot and you know exactly where you're headed with things, and then stop before you go cold. The next night (or whenever) it should prove easy to pick up where you left off. Much easier than starting back up from where things ran cold.
Five pages might not sound like much, but think about 3 months of it collecting. That's over 400 pages written as bare bones of the story. With the second draft, entering all of that into my laptop, it will quickly grow as minimally detailed scenes are fleshed out and dressed in their Sunday best.
You don't have to write 1,000 words everyday. But if you think of yourself as a writer, or you want to think of yourself as a writer, you just need to commit to writing everyday.
