Process.

It follows from all this that there is no technique that can be discovered and applied to make it possible for one to write. If you go to a school where there are classes in writing, these classes should not be to teach you how to write, but to teach you the limits and possibilities of words and the respect due them. One thing that is always with the writer—no matter how long he has written or how good he is—is the continuing process of learning how to write. As soon as the writer "learns to write," as soon as he knows what he is going to find, and discovers a way to say what he knew all along, or worse still, a way to say nothing, he is finished. If a writer is any good, what he makes will have its source in a realm much larger than that which his conscious mind can encompass and will always be a greater surprise to him than it can ever be to his reader.
