I read this quote during a brief time when I had delusions of actually being a good singer. I loved this quote and it has stuck with me, even if I'm still an off-key, toneless singer.
Too often when we start to develop our writing talents and skills, we immediately look to see how everyone else is doing it and we attempt to imitate them. We all have a true writer's voice that is uniquely ours; when we find that individuality, we can truly excel. That's when we don't just write, we create.
