I got very interested in so-called “knockout mouse” technology. Knockout mouse is a way to study the function of genes. You know, both human and mouse have approximately 20,000 genes. With knockout mouse technology, we can select one gene out of those 20,000 genes, and completely destroy that one particular gene so that we can understand the function of that particular gene. I got very interested in that technology. It was 1992 or 1993 when I graduated from my Ph.D. school. So I decided to study — I decided to learn about knockout mouse technology. But at that time in Japan, only a few scientists were working on knockout mouse technology. That’s why I decided to move to the States, San Francisco

Ultimately, it’s a man who was teaching us English Literature in what we call matricula, the last 2 years of high school. He really was quite extraordinary. When he spoke of a Shakespearean play, you almost thought that he grew up with Shakespeare! He was very good, yes. A black guy who was fantastic and gave us a deep love for literature.

they did what good teachers are meant to do, which is inspire you to love literature.

Number two I’d say to young people, be curious.

Find the friends who do that. Find the friends who never tell you that you can’t do it, but who point you in the right direction, hold you when you fail, and push you when you need the push. Those are hard friends to value sometimes, but they are the best of friends.

Because I have to read everything I write and edit it. So I’m not a natural writer. She’s more a natural writer than I am. But I can do what I need to do to give myself enough time to write papers, edit them, before I turn them in.  And that’s what I still do.

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.

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.
