...Irwin Shaw, The Art of Fiction No. 4
But don’t forget that almost every writer will tell you that events that happened to him before he started writing are the most valuable to him. Once he starts writing he seems to observe the world through a filter. I believe that’s true about writers: that the unconscious observation of things, a kind of absorbing of life that goes on before he becomes a writer, that is what is most useful to him. When he starts observing things professionally and taking notes and trying to remember, he may collect a lot more but he loses the spontaneous quality and the flow. He becomes too systematic. It’s his job to be, but he never gets anything as valuable as what he got unconsciously. He has become the observer rather than the actor.
