I think one of the most important things that I’ve had to overcome is jealousy from the outside. Of learning that not everybody is going to be my friend.

What I’ve got doesn’t hurt. I’ve been lucky. The treatment has been benign. I don’t know if I could concentrate if I was in pain. I’ve never had to stop.

That was a direct challenge to the NFL constitution, which said you have to have a three-quarters approving vote if you’re going to move your franchise. And we had Davis challenge that in his move from Oakland to Los Angeles. And it was sitting there in the constitution, and I couldn’t just say, “Oh, I’m not going to press this.” I brought it to the attention of the owners, and I said, “I think we have to defend this constitution.” So we had two trials over a couple of years.

The second filter is to gravitate towards working on hard things. I’d love to tell you I was an immediate success after leaving Stanford… I wasn’t. Even a decade later, I felt like I wasn’t on the right path, and it took me a while to find my footing. Until I applied to Google. I had my final interview there in 2004, it was April Fool’s Day and the day Gmail launched. So when my interviewers asked me about it, I wasn’t sure if it was a joke or a real product. That’s because at the time, one gigabyte of free storage for everyone felt super ambitious, and almost impossible. A couple years into the job, I got my chance to work on a seemingly impossible problem, too. It was around this time that the internet was moving into a new phase. The web was evolving from simple web pages to rich applications. There was a group of us that felt we could reimagine the browser to be much better and faster, and we had an early prototype that we thought was pretty good. Internally there was a consensus that building a browser would be incredibly difficult, requiring hundreds of engineers; we had a group of about ten. The consensus was right. It was going to be really hard. In some ways we were naive, and it's good to be a bit irrational when you approach new things. And in 2008, we launched what we thought was a great browser. We had eight million users in the first twenty-four hours, and the reviews were really positive. And then user growth stagnated. After a year, we had around two percent share. I remember Steve Ballmer, the CEO of Microsoft, made fun of Chrome in an interview and called it a rounding error. It could have been demoralizing. But with that California optimism, I told the team that the fact he went out of his way to dismiss us meant we were doing something right. We kept going, setting highly aggressive stretch goals to keep the team pushing. We rapidly iterated, shipping the browser every six weeks while others shipped one maybe every six months to a year. Success began to follow. Working on hard things has taught me a lot: It typically attracts other great and optimistic people. And even if you miss meeting the high goals you set, you’ll still achieve something great. So when you have the choice to work on something hard — say yes. Do what excites you

Well, I’ve completely reneged on that one and within a very short time, I think within three or four years.…Well, it has now been shown that it occurs very commonly in fishes, particularly cichlid fishes. So here’s another thing where my intuition was wrong.

Anyhow, I talked it over with my mother, and she said, “Well, if that’s what you want, go right ahead.” She was a wonderful woman. And so I did.

Unfortunately I have too many projects going. Two of them, fortunately, are already in the editors’ hands. One is this book on the birds of Northern Melanesia I’m doing with Jared Diamond, and that deals with speciation and particular ecology, biogeographic dispersal and all the other questions.

The interests of a person plays a considerable role. For instance, people who are born naturalists should choose different professions than people who have a spectacular mathematical talent. I think it depends on a person’s talent, what he should choose and what he should love. If you don’t love what you’re doing, you’re not going to do a good job.

Primarily to show, and you will think that this doesn't need showing, but lots of people would disagree with you. To show that biology is an autonomous science and should not be mixed up with physics. That's my message.

My father had a wonderful library, and we always bought books galore, and I devoured all the books of explorers that went to various places in the world. I admired what Humboldt had done and Bates and Darwin and the Swedish explorers, Sven Hedin and others. I was dreaming all the time about someday being an explorer, going to the tropics, going to the jungles, seeing new things, discovering strange animals and so forth, but of course it was a dream world.
