I used to work very long hours. Then I started to realize that the stuff that I was writing in the late afternoons, I was generally throwing out. So I quit earlier than I used to.

What would be the good of rushing? You want these books to last.

I sometimes feel that if your book sells more than 20 years, then there's something in it that you can say, gee, I did something that endures, that's timeless

If you really want to show power in its larger aspects, you need to show the effects on the powerless, for good or ill - the human cost of public works. That's what I try to do, show not only how power works but its effect on people.

It's very easy to fool yourself that you're working, you know, when you're really not working very hard. I mean, I'm very lazy. So for me, I would always have an excuse, you know, to go - quit early, go to a museum, you know. So I do everything I can to make myself remember this is a job. I keep a schedule.

I am trying to make clear through my writing something which I believe: that biography- history in general- can be literature in the deepest and highest sense of that term.
