In the series I’ve got massive slabs of dialogue so I had to understand the scientific principles involved and then fake it to credibility.

I did it because that’s what it was going to take. I really wanted it. I had an older brother, and he was bigger and smarter, and when you’re a kid, you’re trying to catch up all the time. I think that that’s where it kind of came from, just that little brother syndrome. I was just trying to be something, trying to make myself worth something. It was proving it to other people and proving it to myself at the same time. I needed that.

Carrie helped me keep to a strict rhythm, but all the essays took shape in very idiosyncratic ways.

Do I have a muse? Well, I don’t know if this is an adequate answer, but I suppose my muse is the people of South Africa. I’ve often said that the little — or maybe the lot — I know about loving and hating was taught me by South Africa. Now that’s a big debt. When you owe that much to a situation that has shaped your conscience, your heart, your whole life, you’re profoundly indebted.

I have a pretty great life,

I’m surrounded by 60 people that are doing smart things all the time. They probably don’t realize it but I’m learning constantly from every single one of them.

CEOs are pinch hitters. We should be working on the things that nobody else can or nobody else is.

I begin each morning, I do every single morning exactly the same way, I begin each morning by doing my highest priority work first. I have a very clear priority list and I start from the highest priority work first. Before I even get to work, my day is already a success. I've already completed my most important work and can dedicate my day to helping others.

I try really hard not to have Outlook manage my life.

Of all of the things that I value most about my abilities, intelligence is not top of that list. My ability to endure pain and suffering, my ability to work on something for a very, very long period of time, my ability to handle setbacks and see the opportunity just around the corner I consider to be my superpowers, and I hope they're yours.
