It's a visual world and people respond to visuals.

I try to ask visual questions. I'll ask what someone was wearing, if that seems relevant. If possible, I'll walk over the same ground that they're depicting. Of course, I can never get it precisely as it was.

I tried to draw people more realistically, but the figure I neglected to update was myself.

When I was there, something clicked in my head; I found myself interviewing people, searching out facts and figures. Later on I became much more self-conscious of what I was doing.

And I think I find, I know a lot of people around, in different cities, and so it's not - it might sound strange - but it's not that hard to say good-bye, because I know there's other people where I'm going. I can sort of fit in in a lot of places.

Oh, it's essential. I mean, you have to - if I'm writing about the Middle East, I have to go there, and if possible, stay long enough to get a real feeling for what's going on.
