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.

Nothing comes to my desk that is perfectly solvable. … Otherwise, someone else would have solved it. So you wind up dealing with probabilities. Any given decision you make you'll wind up with a 30 to 40 percent chance that it isn't going to work. You have to own that and feel comfortable with the way you made the decision. You can't be paralyzed by the fact that it might not work out.

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.

I looked straight across at the clock and I was disappointed with the time. I should have run under 49 and I didn't. And I knew I had a lot more in me.

But my answer is this: inspiration is not the exclusive privilege of poets or artists generally. There is, has been, and will always be a certain group of people whom inspiration visits. It’s made up of all those who’ve consciously chosen their calling and do their job with love and imagination. It may include doctors, teachers, gardeners – and I could list a hundred more professions. Their work becomes one continuous adventure as long as they manage to keep discovering new challenges in it. Difficulties and setbacks never quell their curiosity. A swarm of new questions emerges from every problem they solve. Whatever inspiration is, it’s born from a continuous “I don’t know.”

All sorts of torturers, dictators, fanatics, and demagogues struggling for power by way of a few loudly shouted slogans also enjoy their jobs, and they too perform their duties with inventive fervor. Well, yes, but they “know.” They know, and whatever they know is enough for them once and for all. They don’t want to find out about anything else, since that might diminish their arguments’ force. And any knowledge that doesn’t lead to new questions quickly dies out: it fails to maintain the temperature required for sustaining life.
