One of the few things I know about writing is this: Spend it all, shoot it, play it, lose it, all, right away, every time. Do not hoard what seems good for a later place in the book, or for another book, give it, give it all, give it now.

I cannot cause light; the most I can do is try to put myself in the path of its beam.

Caring passionately about something isn't against nature, and it isn't against human nature. It's what we're here to do.

A work in progress quickly becomes feral. It reverts to a wild state overnight. It is barely domesticated, a mustang on which you one day fastened a halter, but which now you cannot catch. It is a lion you cage in your study. As the work grows, it gets harder to control; it is a lion growing in strength. You must visit it every day and reassert your mastery over it.

You can, in short, lead the life of the mind, which is, despite some appalling frustrations, the happiest life on earth. And one day, in the thick of this, approaching some partial vision, you will (I swear) find yourself on the receiving end of - of all things - an "idea for a story," and you will, God save you, start thinking about writing some fiction of your own. Then you will understand, in what I fancy might be a blinding flash, that all this passionate thinking is what fiction is about, that all those other fiction writers started as you did, and are laborers in the same vineyard.
