Submit your “I Write Because…” response by reading about the project then writing your response. I think you’ll find that when you have nothing more to say on the subject but you push a little harder, you’ll go deeper and you’ll discover something about your writing, about your motivations, that you hadn’t realized.
I’m looking for something that is both from the gut, but crafted, revised, polished. Also your response should be in the 500 word range.
