When Jeff Zaslow's column appeared in the Wall Street Journal (WSJ), about a dozen publishers emailed me, asked if I would be willing to write a book based on it. (I found this laughable, since at the time the palliative chemo was not yet working, and I thought I was down to about 6 weeks of good health). When the palliative chemo started working and we had some breathing room, I mentioned this to Jai, and she told me she wanted to do it. She was, in fact, quite emphatic. We had always talked about my "writing the manual" for her and the kids in my remaining time, and Jai felt that if it were a "real" project, I might take it much more seriously.

As far as the Carter Center's concerned, I would like to see guinea worm completely eradicated before -- before I die. I'd like for the last guinea worm to die before I do. ... I think right now, we have 11 cases. We started out with 3.6 million cases. And I think we have two cases in South Sudan and one case in Ethiopia and one case in Mali and seven cases in Chad. That's all the guinea worms in the world, and we know where all of them are. So obviously, that would be my top priority.

I still don’t understand everything about the ribosome. I must say that the more lectures I give and the more questions that I get, the more thoughts they trigger. And also, we are now interested in the proto-ribosome, how life started. So we are trying to understand this and this really excites me, not just from the point of view of philosophy, we are trying to show it.

I would like to write a play which doesn’t disappoint me 20 years later.

Now I try to protect one hour in the morning and one in the afternoon where I turn off Slack, and I don't check email. I might read, or write in a journal, or just go for a walk. It's become one of the most important parts of my day. It's when I'm most creative, and when I hit on ideas that can take the company in new directions.

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.

Queremos crear un ambiente familiar en donde no todo sea fácil, en donde no todo les caiga del cielo, sino que puedan construir su propio camino y tengan ese sentido de desesperación y esa hambre. Eso significa también que todo ese dinero no se les va a dejar a ellos. Se les dará muchísimo amor, como les damos, y muchas oportunidades de educación y de desarrollo, pero todo ese dinero no es para ellos.

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.

Moving closer to work. I live in São Paulo, Brazil, and I used to spend an hour or more in traffic every day, just sitting in the car getting frustrated and anxious. It was a waste of my time.

The simplicity and yet profoundness of the above logic leads us to conclude that for us the most natural and truthful path is to invest this wealth until "our last check bounces", as one of our personal heroes, Chuck Feeney, likes to say.
