I have a bunch of rules for myself. You stop at every village, you ask what the situation is like between this village and the next village, you look for fresh tire tracks. If there are any land mines in the area, then you always want to make sure you go on fresh tire tracks to reduce the risk of mines. You carry a certain amount of money so that if some soldiers with guns want to rob you — no fuss — you give them a decoy wallet or some other money to make them happy, and you just learn to kind of be soothing with unpleasant people.

My job is to not be easy on people. My job is to make them better. My job is to pull things together from different parts of the company and clear the ways and get the resources for the key projects. And to take these great people we have and to push them and make them even better, coming up with more aggressive visions of how it could be.

Treat writing as a job. Be disciplined. Lots of writers get a bit OCD-ish about this. Graham Greene famously wrote 500 words a day. Jean Plaidy managed 5,000 before lunch, then spent the afternoon answering fan mail. My minimum is 1,000 words a day – which is sometimes easy to achieve, and is sometimes, frankly, like shitting a brick, but I will make myself stay at my desk until I’ve got there, because I know that by doing that I am inching the book forward. Those 1,000 words might well be rubbish – they often are. But then, it is always easier to return to rubbish words at a later date and make them better.

For a photographer — it’s like actually taking a picture is like five percent of what I do. And the rest is research, reading, contact, setting things up, making contact, getting access, making people feel comfortable, doing the reporting, doing the interviews, getting the captions. It’s not getting there physically, the logistics on the ground. I mean, literally, taking a picture is the easiest part of my job.

But one of the things that my father did was to let me read comics. Now people used to say that’s bad because it isn’t — it spoils your English but, in fact, letting me read — I devoured all kinds of comics — fed my love for English and my love for reading but I suppose if he had been firm I might not have developed this deep love for reading and for English, which stood me in good stead when I later went into hospital for 20 months. I did have something to do. I had — as things maybe got a little bit more serious, I was given a diet — we didn’t have too many books but my father was keen that one read things like Aesop’s Fables and Lamb’s, Tales from Shakespeare . I didn’t read the originals but I read these stories that describe what Shakespeare was saying in the plays and that possibly was something that sharpened your appetite for later.

Dream. Dream. Dream. Be like God, dream because God believes in you young people. Most of God’s best collaborators and partners have been young people. Joseph, David, Jeremiah, St. Francis. They are young, young, young. And in many ways Jesus was young. Many of those who have been God’s best works — fellow workers have been young. And don’t allow oldies to fill you with their cynicism and disillusionment. Dream. Dream that this world can become better as you do dream, in fact. I mean, when these young people go off and work as Peace Corps and other volunteering groups in poverty stricken places where they don’t get any better headlines for dreaming the good things. Dream. Dream. Dream. Dream that this can be a world without poverty. Dream that this can be a world without war. Dream that this is a world that will recognize that every human being matters.

I know that for a very long time my consuming passion, which was confirmed when I contracted TB — I had TB when I was about 12 or so — was I wanted to be a physician and when I got TB I was even more determined. I want to be physician so that I can find a cure for the scourge. And, in fact, I was admitted to medical school. If we had had the funds maybe today I would have been a physician.

So a great deal has changed, but we in the Truth and Reconciliation Commission said, “Watch it. You can kiss reconciliation and forgiveness goodbye, unless the gap between the rich and the poor — the haves and the have-nots — is narrowed, and narrowed quickly and dramatically.” So yes, we face very, very considerable problems.

Just look at a Dalai Lama and Mother Teresa and Aung San Suu Kyi and Nelson Mandela, and you’ll see that one of the outstanding characteristics of each one of these is how they have poured themselves out prodigally on behalf of others, of their being so utterly selfless.

I used to be “Mister Disinvestment.” Now I would like to be Mister Investment and say, “Come! Come and be part of an exciting, exhilarating process. Come in! Come in on the ground floor and see a people do something that’s probably never happened before, people seeking to become something radically different from what their antecedents would have made us believe they were likely to become.
