If I had to make the welfare decision again tomorrow, I’d sign it again tomorrow. We had a 60 percent reduction in the welfare rolls. We had an enormous percentage of poor people move into the workforce, start middle-class lifestyles, and when we had a brief tech recession of six months in 2001, after I left office, people who had moved from welfare to work were less likely to be laid off than the general working population. So I would do it again.

Don’t write in public places. In the early 1990s I went to live in Paris. The usual writerly reasons: back then, if you were caught writing in a pub in England, you could get your head kicked in, whereas in Paris, dans les cafés . . . Since then I’ve developed an aversion to writing in public. I now think it should be done only in private, like any other lavatorial activity.

I’d read some of the things that Don Glaser wrote, for example, and they’re imaginative physics, they’re not quite such good biology. There was a consensus that said you had to be able to reach out from physics and get to some of these things you’d like to, but then you have to know enough about the biology that the whole thing makes sense. And you really have to present things in such a way that a community develops. I didn’t realize that at the time, but certainly one of the important things of what I did had to do with enabling people who came from physics, or who came from biology, become a community, working on not just one little problem or piece, but somehow collectively working together toward trying to get an understanding.

Design is a funny word. Some people think design means how it looks. But of course, if you dig deeper, it's really how it works. The design of the Mac wasn't what it looked like, although that was part of it. Primarily, it was how it worked.

I’ve had a long career as a writer, and a good one, in good company. Here at the end of it, I don’t want to watch American literature get sold down the river. We who live by writing and publishing want and should demand our fair share of the proceeds; but the name of our beautiful reward isn’t profit. Its name is freedom.

Right now, we need writers who know the difference between production of a market commodity and the practice of an art. Developing written material to suit sales strategies in order to maximise corporate profit and advertising revenue is not the same thing as responsible book publishing or authorship.
