I do have a strong sense of an order in the universe.

On the whole, I don't want to think too much about why I write what I write. If I know what I'm doing ... I can't do it.

I think we are well advised to keep on nodding terms with the people we used to be, whether we find them attractive company or not. Otherwise they turn up unannounced and surprise us, come hammering on the mind's door at 4 a.m. of a bad night and demand to know who deserted them, who betrayed them, who is going to make amends.

It is impossible to think of Howard Hughes without seeing the apparently bottomless gulf between what we say we want and what we do want, between what we officially admire and secretly desire, between, in the largest sense, the people we marry and the people we love. In a nation which increasingly appears to prize social virtues, Howard Hughes remains not merely antisocial but grandly, brilliantly, surpassingly, asocial. He is the last private man, the dream we no longer admit.

Once I get over maybe a hundred pages, I won't go back to page one, but I might go back to page fifty-five, or twenty, even. But then every once in a while I feel the need to go to page one again and start rewriting.
