Planning
So I moved on. A fwe days before the challenge was supposed to start, I started an outline-less story, figuring that by the time the challenge started, the story would be rolling along on its own momentum and I'd be able to get plenty of words done on it. At least, this is what I hoped, even though I know I do much better when I have an outline to work from. I should be able to write without one, I thought. I'm a writer; I'm creative. And people keep saying that outlines get in the way of creativity. But I just don't write well like that. When I can separate the planning part from the wrong part, I can devote more attention to both, and I don't have to worry about losing track of my ideas. With this story, I had no idea where I was going with it. I considered pushing past it and forcing myself to write the story, but I had a bad experience a year and a half ago where I forced myself to finish an aimless and dying story and thus killed my creativity for months.
Next plan: Interconnected short stories. Deep down, I knew it wasn't going to work. But I tried anyway. And failed. And had to accept the fact that I just wasn't going to do the challenge this year.
So, back to planning.
I feel kind of guilty about all this planning I'm doing. I'm doing the 2YN class, where we've just finished character creation and have moved on to worldbuilding. I'm also doing worldbuilding for a series that I've been wanting to write for a very long time. I've got several ideas stewing in the back of my mind; I play with them every so often, and I can feel them bubbling away back there, soon to explode into something new and better. And I'm tentatively working iwth one of those ideas, trying to solidify it on paper. (This is hard for me, though; the 2YN novel is my current project, and I'm not used to splitting my creative focus like this.) All my projects are in the planning stage.
Don't get me wrong, I've been writing. (My February word count was something like 27,000... though that did include that very long short story.) But those words are all planning. They're details about plots and characters and worlds. They're not actual story words.
I know the planning part is just as necessary as any other. (Some people can skip it, and do better that way; I'm not one of those people.) But it still feels like I'm not doing real writing.
