[My father] used to say all the time, “You’re in a struggle, but if you get in a fight and lose your temper, you’ll lose the fight. So don’t get mad, get smart.”

My parents also said, “Don’t follow money. Follow your heart and you’ll be successful.” That’s all they told me and my sisters.

“David, you are going to walk among kings.” This was my mum’s prophecy when I was small. My father is from a royal family in Nigeria, so I interpreted it that way. Remarkably, she was right: I went on to play King Pelasgus, Henry VI, Martin Luther King and Seretse Khama.

I think he was a great philosopher. He had a wonderful theory that you live in the “now,” which I think is important. Along with living in the moment, you also have to assume the responsibility that goes along with it, and you don’t take your position lightly. But it also means that you get the full value of the moment that you are living, so you don’t look back on your life and say, “If only I hadn’t wasted time, if only I had done this.” You do the best you can. It was wonderful to be able to go home after a performance, and think, well it wasn’t maybe so good, but it was the best I could be at that time.

Too many people who go to the best schools, and get great grades, are confronted with a choice of trivial work that is very high paid, and has some sort of surface status, like senior partner in a law firm, or corporate executive, but most of the work can be done by anybody.

We used to converse at dinner time around the table. Parents and children. We talked about all kinds of issues. From local, neighborhood issues to world issues. It was back and forth, very lively, and very critical. During our early years my mother would relate historical sagas to us for five or ten minutes every lunch hour, when we would come home from school, and it would be continued the next day. I think that built into us a sense that freedom involves responsibility. It isn’t just waving flags and saying, “Look how free we are,” while people’s rights are being trampled sometimes overtly, sometimes beyond their control.

I think three things. One is the great advances in auto safety. I mean, there are tens of thousands of people being saved every year because cars are safer, and millions of people over a decade, injuries prevented. I think that’s a good example of the need to make technology more humane. We may benefit from a lot of technologies, but they exact a cost. Emphysema, cancer, soil contamination, contaminated water, death and injury on the highway. We’ve got to put more effort on making them more humane.
