The closest to inspiration was my beloved fifth grade teacher, Mrs. Ponti, who I’m delighted lived long enough to get that book’s dedication. I exchanged Christmas cards with her for the rest of her life. She was a wonderful woman. I think the main way she inspired was by respecting students’ interests. She herself knew very little science. Science was not formally taught at all, as far as I can remember, at grade school level. She realized there were a group of us who were interested in science, so she would let us sit by ourselves in the back of the classroom once a week for a couple hours, and she got books for us and discussed science. So I suppose she was a very good model for good students.

My dad had such a big influence on me, he was kind of all that wrapped into one. Even if we had a guest speaker at our school, or read something in class, or heard about it, I would always go back and check with him. “Is this right? Would you agree with this, Dad?” He had a big influence on me, so he was the guy I went to for advice and the guy I listened to, and still do today.

The early influence in my life I think was my father. That’s the earliest influence. He and his circle of friends. Usually, in our society, children are supposed to be neither seen nor heard. When elders are around, they’re supposed to very respectfully leave them alone. But I was curious. I just loved their debates. They used to get excited over issues, and so somehow I was allowed to eavesdrop, unlike the other children. And I picked up some of the ideas that they had, and I would ask questions. I was known as the questioner. Afterwards, I would ask questions, and my father would indulge me by trying to explain things to me. So that’s one of the reasons I consider him the earliest influence. And also, he had a small library, and I used to go into his library and try and read the books which I found there. Later on, as my circle of adult acquaintances increased, I think the next influence on me was my uncle, the Reverend I.O. Ransome-Kuti, who was another very erudite person, a great educationist. I used to visit them in Igbein, where he lived with his wife and they ran a school. So on weekends sometimes I would go there. And of course it was the usual story. I wanted to listen to them discussing and so on. Don’t misunderstand me. I was also very playful. I loved disappearing by myself, climbing trees, all that I did. But additionally, I was just fascinated by the whole discourse. Exchange of ideas between adults just used to fascinate me for some reason. I was never tired of listening to them. So my uncle was my next great influence.

I definitely had some teachers who were important. My fifth grade science teacher, Mr. Jake, was really the first teacher to express confidence in my academic abilities because I was the only person who could identify a rock, which was obsidian and it was because of the reading that I had been doing because after I got through with the animal books, I went to plants, and when I finished all the plant books, I went to rocks because we lived on the railroad tracks and there were a lot of rocks, so I became an expert in geology, and this was while I was still a dummy in the class. So, it was like the first time that I had an opportunity to raise my hand and demonstrate my knowledge because nobody else knew the answer. Everybody was absolutely flabbergasted, but Mr. Jake said to me, “Benjamin, that’s incredible.” He said, “Why don’t you come by the laboratory after school and we can talk about starting a rock collection for you.” And, from there I started going to the laboratory every day, getting involved with feeding the squirrel, a red squirrel named Maynard. There was a tarantula, crayfish, a Jack Dempsey fish and I got involved in all this stuff. There was a microscope and I started looking at water specimens and learned all about paramecium and volvox and amoebas, and it was just incredible. That really was what started me on my way.

I applied to one firm in every sector. This was the most half-hearted job search. “I’ll apply for that management consulting firm and this investment bank…” and I applied for five jobs altogether, because my heart wasn’t in it. And thankfully… I’m so glad I didn’t get any of those big jobs! Because that made this decision easier.

The Fountainhead , I think, pretty much saved me in the initial years of Teach For America. I loved that book, but I’m not sure books were the seminal thing that guided my path. ... I think it was sort of about “the creator against the world,” and I was probably feeling at that point that I was up against lots of boulders, to pull off the big idea of Teach For America.

And the most fulfilled, centered, grounded, happy people I know are people who made the choice to be part of an effort to actually make the world a better place. ... I would say, to me, the path of least regrets is to at least make a short-term commitment to say, “Let me work to make a real difference in the world.” The worst that could happen is you decide to move into something else later, but you’ll always take with you what you’ve given and what you’ve gained through that experience.
