The kind of hope I often think about (especially in situations that are particularly hopeless, such as prison) I understand above all as a state of mind, not a state of the world. Either we have hope within us, or we don't.

Yes. Today has been really stressful. We had a workout this morning. It went okay. And then just that five and a half hour wait or something. I was just shaking, could barely nap. I've just never felt like this going into a competition before. And I tried to go out here and have fun. And warm up in the back went a little bit better. But then once I came out here, I was like, "No, mental is not there. So I just need to let the girls do it and focus on myself."

The real problem is that the pain actually gets worse. You have created massive acidosis in your muscles so there is a huge quantity of hydrogen ions and the pH in your blood changes. For 15 minutes you lie there thinking, "God, this is really bad. I'm going to die. It has never been this bad before." And every time you think exactly the same thing. You have to lie to yourself by saying you're not doing a second set. Then, without moving for 15 minutes, almost to the second, I would roll over and think, "OK, I think I can do a second set now." During those sessions I have never felt more alive or so close to death.

Never stop when you are stuck. You may not be able to solve the problem, but turn aside and write something else. Do not stop altogether.

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.

Un constructor.

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.

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.
