The world would say it was failure. But the difference was so small between us. They played great, but they lost.

Well yes, but like I said, small mistakes or small failures. We take small failures very often. We have failures in investment. We have failures in operation, but no big mistakes or big failures. How do we take that? Like ordinary business.

At first the research did not seem to be particularly interesting – I carried out a systematic search for processes that might destroy the CFCs in the lower atmosphere, but nothing appeared to affect them. We knew, however, that they would eventually drift to sufficiently high altitudes to be destroyed by solar radiation. The question was not only what destroys them, but more importantly, what the consequences are.

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.

I didn’t start out thinking I would be a children’s book author. I didn’t start out thinking I’d be an author at all. If you know my biography, you’ve heard that I spoke Spanish before I spoke English and struggled until my young adulthood with learning how to speak and write English properly. It was Philomel Books and [publisher] Jill Santopolo who came to me and proposed writing a children’s picture book about my life.

Well, what's very interesting is that those people read our opinions which can be, at moments, rather animated. An animated exchange in writing among the justices. And many people who read our opinions think we have to be at each other's necks constantly. It's interesting we're not. When we're talking about cases at our conference it's generally a conversation. It's really a talk about what our perspectives are and why we have reached the conclusions we've reached.

My diabetes. You couldn’t go into law enforcement [with that illness]. Now I believe in some police forces you can do that. It wasn’t possible back then. But for a then-8-year-old to have my ambition — my dream — destroyed, broke my heart.

I think I have been mentored by many extraordinary judges in my career, but there’s one in particular that probably changed the course of my life on the court. And that’s Justice John Paul Stevens and the one year we overlapped.

The second, probably, and I didn’t talk about it in my book, which is always interesting to me, because it didn’t come up within a lesson, okay, within the book teaching me a lesson, but the second was Don Quixote. And that ties in so much to the optimistic part of me, this idea of tilting at windmills, whether they’re real or not. The imagination of them, what fueled that man, that love, that idyllic sort of quest. That can be life sometimes. We don’t always achieve what we end up hoping for. We can work very, very hard at things and come up short. But I take comfort from having dreamt the dream. From having taken the steps, the quest, to undergo the quest of trying to reach them. If at the end you don’t, you’ve had the journey, and I always think the journeys are valuable. They give you lessons, they give you memories. They help you meet people, they help you have an adventure in life. And so for me, that probably, when I’ve read that book, I understood that I was okay. Being optimistic wasn’t a bad thing. It was actually a very good thing.

I tell the kids that I speak with on these book tours that my greatest legacy will be the last child who remembers something I’ve said or done that helped them manage something in their life. Once I die, I will be alive through that last child whose life I helped make easier in some way. And that, I hope, could be a very long time.
