We seek structure in the world around us. Life rarely provides it. But we find this structure by creating it.
Our observations of the people around us, an amalgam of experiences and emotions, lack this structure, and yet we place it upon them — and ourselves. We listen to their stories of their childhood or some other experiences from their lives and we come to think that there was a direct cause and effect. It is hard to accept that life is more complicated than that, even when we all know that to be true.
A writer attempts to create that structure through their work. It is only in creating a world where we can truly find one that makes sense.
