Never give up your passion for learning. And zoom out of your field before you zoom in. Some of my very best business insights have come from reading around subjects. They have come from approaching questions at a strange angle, from thinking about them from a different point of view. A lot of the knowledge that has really given me an edge in business has come from history, psychology, even chemistry. Connecting seemingly unconnected dots is what has served me well.

Life doesn't offer you the perfect opportunity at the perfect time. Opportunities come when you least expect them ... Rarely are opportunities presented to you in a perfect way. In a nice little box with a yellow bow on top. ‘Here, open it, it's perfect. You'll love it.’ Opportunities -- the good ones -- are messy, confusing and hard to recognize. They're risky. They challenge you.

Learn by doing, not learn first, then do. The way you discover what it is you like to do in life is by doing first, then learning about it.

Well, 20 is still slightly too old, but like my 18-year-old self, I would just tell to – I would say to just not bother going to college at all. Because like the year that I spent at Berkeley was a total waste of my time, basically. Not because there’s anything wrong with Berkeley, but because I just wasn’t passionate about what I was studying, and there’s no – there was no point in me like grinding out a year of studies that I didn’t care about.

But the book I give right now in this time of so much despair is Viktor Frankl’s Man’s Search for Meaning, where he really looks at people in the Holocaust and asks himself, why did some just sort of crumple up and die and others stayed resilient and strong? And that at the end of the day, no one can take our dignity away from us.

One of the biggest lessons of my life, Krista, has been that we can’t separate the world into monsters and angels and that there’s nothing like loving people and knowing friends who played different roles in the genocide, including being perpetrators, that makes you have to confront that most raw element of what it means to be human. And the only conclusion I could make was that there are monsters and angels in each of us and that those monsters really are our broken parts — they’re our insecurities; they’re our fears; they’re our shames — and that in times of insecurity, it becomes really easy for demagogues to prey on those broken parts and sometimes make us do terrible things to each other.

Email. Or call a good friend. Reading this reminds me that I should instead read poetry. Or write.

That human beings are selfish. I don’t believe it. We have angels and monsters inside each of us. What we need to do better as a society is create systems and opportunities to bring out our most generous.

I am lucky not to have felt burned out. That probably goes back to what energizes me. I get great energy from connecting with people we are serving especially. And if the work feels too hard, there is nothing like a long run to revive my spirit…

A new generation that is determined to use the tools of capitalism without being controlled by it. To solve big problems of poverty and of the environment. We now have more tools, skills, understanding, and awareness than ever in history—so solving those problems is within our reach.
