Writing is like walking through the fog. You start with only the ground you're standing on and a distant idea--a destination at which you hope to arrive. You find your footing in a little bubble of visibility. You know who you are, and just maybe an approximation as to where. And with your fleeting goal in mind, you stumble off through the mist. Shadows appear and take form. A tree. A dirt road. An incline. A wall. As you come to understand it, you build the world around you.
