They’re not failures, you try something and it doesn’t work, and some people, you know, get fed up with this, and I’ve known some of my friends and colleagues who have just decided to give up science because they can’t stand it, but I’ve always decided, you know, if it doesn’t work, forget it and start planning the next experiment, and that’s always exciting.

As I was lazy and rarely did my homework, I finished high school with a rather mediocre exam. I almost did not pass in English language. Recently, my previous teachers allowed me to see their report on my high school performances, which included the following statements: Despite the fact that her talents are rather equally spread among many areas of knowledge, her performances are rather different depending on the distribution of her interests. Thus, with her strong display of self will she can be decidedly lazy in some topics over years, while in her areas of interests she performs to a degree far extending that required for normal school purposes.

But after one year of medical school I fled. I realized I would be a very unhappy doctor and I really did not want to be responsible for the inadvertent death of my patients. Leaving medical school was a very unusual decision, especially in Nigeria where it is very difficult to get into medical school. Later, people told me that it had been very courageous of me, but I did not feel courageous at all. What I felt then was not courage but a desire to make an effort. To try.

Don't be scared of the ‘what ifs,’ because the truth is, the only failure is not trying. That's the only way you can fail. Trying and having it not work out isn't failure.

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.

And in many, many parts of the world, if you’re going to deprive a parent of custody of their child, you better give them a lawyer. And we don’t. We have an unequal representation of people in our court system. And that does, I think, provide an injustice that we don’t pay enough attention to.

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.

And I didn’t know at that moment what my impact was. I actually fell asleep that night crying. But the next morning, my mother woke us up, and she said she doesn’t remember this dress, but it was a black with white polka dot dress. And her hair was finally properly combed.  She had for the first time in a year some makeup on, and I knew my mom was back. And that may have been one of the happiest moments of my life.

And I realized that to get them I had to figure out how to study. And I did something that has helped me my entire life, and it’s something I still do, which is when I don’t know how to do something now I start reading about it. Back then I would ask people for help.

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.
