I don't believe in "writer's block" as it is traditionally understood. As a trained scientist, I have spent time researching for the sake of knowledge both neuroscience and psychology, and I have come to believe the experience of our lives is not out of our hands. We are not simply stimulus-response systems, nor are we victims of some spiteful force as "writer's block." We have intention, and we make decisions. Our realities are shaped by the ways in which we associate meaning to our realities. If you are not feeling creative, the single most effective response is to sit down at your art and begin behaving as if you ARE feeling creative (for a writer, that means grab that notebook and start writing; don't concern yourself with what) - behaving the way you do when you ARE feeling creative will stimulate the creative aspects of your brain and be self-fulfilling. The unfortunately reality about being a writer is that you have to write. Not-feeling-like-it isn't a valid excuse for denying your passion.
