I wanted to know. I asked a lot of questions and she would say, "Read, read."…So she inspired me a great deal.

I wish I knew more about Clojure, which is the programming language we use most at Nubank. If I did, I could better understand some of the more complex problems we're trying to solve, and I think I could ask better questions when we're setting priorities. I'd like to be able to communicate at that level with the technical side of our team, and I think they would appreciate it, too.

I think a very big curiosity. I’m very curious and I like to understand things and not only science but also other things where I just try to find out why things work or how things work. Science and nature caught my attention as a small child already. I was growing up in a city but we had a garden and I loved the garden and then often on vacation I was at a farm and I loved these animals and plants and so on, so I was attracted very early on and then we had a very good teaching actually at my … I don’t know whether my teachers really had much of a role because I was determined very early, but then I also did music and I did languages and Literature and so on. I have broad interests actually other than science, but this is really true, this curiosity.

I have also benefited from teaching; as I try to explain my views to students with critical and open minds, I find myself continually being challenged to go back and rethink ideas. I now see teaching and research as complementary, mutually reinforcing activities.

The problem is I'm older now, I'm 40 years old, and this stuff doesn't change the world. It really doesn't. That's going to break people's hearts. I'm sorry, it's true. Having children really changes your view on these things. We're born, we live for a brief instant, and we die.

I didn't see it then, but it turned out that getting fired from Apple was the best thing that could have ever happened to me. The heaviness of being successful was replaced by the lightness of being a beginner again, less sure about everything. It freed me to enter one of the most creative periods of my life.

I don’t think I’ve ever worked so hard on something, but working on Macintosh was the neatest experience of my life. Almost everyone who worked on it will say that. None of us wanted to release it at the end. It was as though we knew that once it was out of our hands, it wouldn’t be ours anymore.

The things I'm most proud about at Apple is where the technical and the humanistic came together, as it did in publishing for example. The Macintosh basically revolutionized publishing and printing. The typographic artistry coupled with the technical understanding and excellence to implement that electronically--those two things came together and empowered people to use the computer without having to understand arcane computer commands. It was the combination of those two things that I'm the most proud of.

I'm convinced that about half of what separates the successful entrepreneurs from the non-successful ones is pure perseverance. It is so hard. You put so much of your life into this thing. There are such rough moments in time that I think most people give up. I don't blame them. Its really tough and it consumes your life.

My job is to not be easy on people. My job is to make them better. My job is to pull things together from different parts of the company and clear the ways and get the resources for the key projects. And to take these great people we have and to push them and make them even better, coming up with more aggressive visions of how it could be.
