Some writers claim to extrude a book at an even rate like toothpaste from a tube, or to build a story like a wall, so many feet per day. They sit at their desk and knock off their word quota, then frisk into their leisured evening, preening themselves. This is so alien to me that it might be another trade entirely.

I started reading poetry in primary school—Victor Hugo, the romantics, and the Parnassians—they were part of the curriculum. In my grandfather’s library there were some anthologies of nineteenth-century poetry. Alfred de Vigny impressed me most; indeed I won a competition by reciting Vigny’s “Moses” with an enthusiasm that touched the examiner. In fact this poem and “La Maison du Berger” are among the most beautiful poems in the French language, unfairly neglected today.

I always say the Nubank story was very unlikely. It was a very low probability event. Again. We were going after these very big incumbent banks. Everybody told me, you know, you're Colombian. You have no idea what you're doing in Brazil. They're going to crush you. Like, don't. Just don't do it. And I did it mostly because everybody told me I couldn't do it. And so, if somebody tells me I can't do something, I want to go do it.

I’d read some of the things that Don Glaser wrote, for example, and they’re imaginative physics, they’re not quite such good biology. There was a consensus that said you had to be able to reach out from physics and get to some of these things you’d like to, but then you have to know enough about the biology that the whole thing makes sense. And you really have to present things in such a way that a community develops. I didn’t realize that at the time, but certainly one of the important things of what I did had to do with enabling people who came from physics, or who came from biology, become a community, working on not just one little problem or piece, but somehow collectively working together toward trying to get an understanding.

I think that it is necessary to implant in children the love for science from the very beginning, and mostly the love for asking questions about the universe, for example why does the sun rise in the morning? Or what allows life on earth? Why earth is so unique compared to the moon? Or about our own body and evolution: what happened to us?

I wanted to be a physician. And I am a physician, so I fulfilled that dream. I did not know anything about science. I did not know what one was supposed to do in science. I wanted to be a doctor, and I became indeed a doctor.

I always chose to surround myself with good people no matter my career. I picked teachers and mentors who promised me a hard life.

I cannot tell you even. I have to ask my son and my wife that were with me in the room because I came to say ”hello,” that I’m leaving. And, I was caught in total surprise. It’s wonderful. What can I tell you? Obviously, it’s wonderful. That’s the climax that every scientist can ever dream of. I will not deny that I am proud for me, for this science, for the state of Israel, for my family, for everybody.

You have to die of something. Let’s say we would be able to cure cancer, or Alzheimer, or cardiovascular diseases. And then what? Should we be young forever or healthy forever?

I never listened to any noise around me. I listened only to my gut feeling and did what I should have
