I faced a number of credibility hurdles linked to gender, youth and the nature of my business venture.

But, of course, we had one problem that the modern mountaineer doesn’t have. That is, this psychological barrier. We really didn’t know whether it was humanly possible to reach the top of Mt. Everest. And even using oxygen as we were, if we did get to the top, we weren’t at all sure whether we wouldn’t drop dead or something of that nature. All the physiologists had warned us that the altitude at the summit of Everest was a very marginal altitude and might be extremely dangerous. So, one had this feeling in your mind all the time that maybe you were pushing things a bit beyond what humans were meant to do and you couldn’t ignore that feeling. But, because of strong motivation, you keep plugging on and you seem to be going okay and nothing seems to be going wrong, so you persist. And we persisted, of course, and ultimately, set foot on the summit.

I realized that the biggest obstacle was my mind. It was the biggest obstacle, and if I could get out of the way of myself, I would grow. So every time I had that attitude, I changed it, and I’d say, “You can. Today you can, and take it one day at a time, and today, I’m going to get up and I’m not going to think about the other six days of this week. I’m going to get up right now, and I’m going to go to the gym, and I’m going to learn about my boxing, and I’m going to be in the moment.” You know, in anything, you hit a wall, and then you have to break through it, and I just had to get out of my own way.

The studios are superreluctant to give final cut. They have so much money riding on these things, so they want a committee to go and rule the roost.

Well, many. I think Steinbeck, for example, was one of my favorites, Somerset Maugham, Hemingway. Quite a few.

Well, I think the most single important issue today is to make sure that nuclear weapons will not proliferate beyond the eight, or nine, countries that already have nuclear weapons; and absolutely make sure that none of these nuclear weapons or this nuclear material will fall into the hands of any extremist or terrorist group, because if they got hold of this material, they would use it. That would be the beginning of the end for civilisation as we know it.

One of my mentors, Tom Frank, a professor of law at NYU, he was really instrumental in making me understand that we need to look at the global picture, and we always need to not take anything for granted, but go very much through a process of critical thinking before we formulate our views. So he was, I think, instrumental in shaping my views as to how to pursue my career in the future.

My sister-in-law and I are working towards the same goal, through different paths: the security of the human family.

Unfortunately, in the case of Iraq, I believe we could have done that through an inspection process. I was calling for a few months more to complete our work. We hadn’t seen indications of weapons of mass destruction. We hadn’t seen indications of nuclear weapons. ... Unfortunately, it didn’t work that way. There was faulty intelligence. There were lots of other considerations that made a decision to go to war tempting, to get rid of Saddam Hussein.

Unfortunately, I don’t. My wife now reads fiction. I don’t have the time to read fiction. My wife reads the fiction and summarizes it to me, but I wish at one point I’ll have time again to read fiction. It is a luxury I cannot afford right now.
