Writer's Block: Please Help?

The best cure for writer's block is writing. Instead of talking about all this, get busy and start writing. You can either try to outline the whole plot, break it into chapters and write the individual chapters, or you can dive right in and start at the beginning. Don't forget, you're just working on a first draft. You're going to re-write it several times before you have a finished product, so let yourself go in that first draft. You can cut out the extraneous matter later - but the important thing for now is to build up momentum and you have to start writing to do that.
