It takes a lot more than inspiration to get me writing. As with things that I consider work, I find it extremely hard to get any writing done unless someone else is imposing a deadline on me. When it comes to inspiration, I experience it more or less perpetually, but it doesn't come easily to me to make use of it of my own initiative. One solution I've tried is to provide writing for people in collaborative works, but that only works so long as the other people stick with the project.
