If I were to give advice to young people, high-achieving young people for example, I'd have to say, don't neglect your family. Politics is important, sitting at the head table is glamorous. Traveling around the world, trying to do something for world peace was wonderful. But family and friends and faith are what really matter in life. And I know that. I see it so clearly now. And so, as they climb the ladder of achievement, I'd simply say, remember what Barbara Bush told those girls at Wellesley: "What happens in your house is more important than what happens in the White House." And it's true. It's so 100 percent true.

Her lesson all the time was “To them to whom much has been given, of them will much be required.”

Harris taught me a lot in that way. Another piece of advice from him was: “Don’t be afraid if your initial plan is not the best plan.” Say you’ve spent all this time and resources in one way, and all of a sudden this little simple idea comes up — do that! Don’t get trapped! Keep your eyes always open.

I think some of the best advice I got as a young session musician — the first time I played on something — they came back and said, “Now just play me half of what you know. Okay, that was impressive, but that’s not what I need here.” So it’s really an exercise on what’s best going to serve the work in front of you, what’s the job that will do that the best.

Very often I had to fight for the recognition of my ideas, particularly since, in those earlier days, I wasn’t in any prominent position where people would listen to me.

There's only one thing where I… if I had the opportunity to live my life over again where I probably would make a change.…I think if I had shortened that period and had earlier begun to work on basic evolutionary theory on history of biology and particularly on the philosophy of biology, I could have achieved some things which now I will never be able to achieve because at age 93, one knows that one doesn't live forever.

And I still remember, and that's the honest truth, as we were leaving his office, he said, 'Well, I give you a fifty-fifty chance to come out alive'. That was Malaita at that time, and... and you can check in the books and will find that that was the... that's why nobody had ever collected there. Well, we made the first collection.

My mentor was Professor Erwin Stresemann, who was at that time clearly the world's leading ornithologist, a man who was not only highly intelligent, but very hard working; he edited two journals, he wrote a big textbook, he supervised students, he sent out expeditions.

Well, you know, the genotype. I'll mention something that nobody ever mentions. Let's say you have now a genotype that makes a certain protein. And that protein, and you can see this in every issue of Science practically, that protein is a very complex structure, incredibly complex. Now how that step from a group of amino acids to that polypeptide [happens] is an enormous jump. I think right now everybody leaves it alone because nobody yet has figured out just exactly how to attack this problem.

What in a way pleases me and makes me very proud, and I probably shouldn't be, is that I am an honorary fellow of the five oldest academies of the world, all five of them and I don't know whether there's anybody else who can say that.
