I feel myself still like a student learning many things doing films.

I got very interested in so-called “knockout mouse” technology. Knockout mouse is a way to study the function of genes. You know, both human and mouse have approximately 20,000 genes. With knockout mouse technology, we can select one gene out of those 20,000 genes, and completely destroy that one particular gene so that we can understand the function of that particular gene. I got very interested in that technology. It was 1992 or 1993 when I graduated from my Ph.D. school. So I decided to study — I decided to learn about knockout mouse technology. But at that time in Japan, only a few scientists were working on knockout mouse technology. That’s why I decided to move to the States, San Francisco

At this school I was allowed to learn things which interested me: French, History, lots of Poetry by heart, and above all Riding and Swimming. The impression of those years makes a pleasant picture in my mind, in strong contrast to my earlier schoolday memories.

Number two I’d say to young people, be curious.

Apenas me despierto, a las 5:00 a. m., cuando voy a hacer deporte. Es lo primero que cojo cuando me despierto. No es la mejor práctica, pero sí desde tempranito.

Vicky, qué pregunta más difícil (risas). Voy a hablarle de los casos que nos han inspirado, como Charles Feeney, cofundador de los Duty Free Shop en los aeropuertos. Él hizo eso en los años ochenta. Se volvió uno de los hombres más ricos del mundo cuando vendió su compañía e inmediatamente se dedicó a la filantropía y gastó todo su dinero en metas sociales.

In the first few months of Nubank, I asked everybody to be here by 8:00 a.m. every day. I saw it as a test of people's commitment, and I was pretty rigid about it.

Los diferentes trabajos en los que he estado, después de mi graduación, han sido de 100 y 120 horas a la semana, especialmente empezando con Nubank. Básicamente vivía en el lugar de trabajo. Empezamos la compañía en una casa de dos pisos. Mi cofundador vivía en el segundo piso. Yo básicamente dormía en el primer piso, o pasaba muchas noches en el primer piso. No salimos de esa casa por seis o 12 meses porque trabajábamos como locos.

Un constructor.

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.
