They’re not failures, you try something and it doesn’t work, and some people, you know, get fed up with this, and I’ve known some of my friends and colleagues who have just decided to give up science because they can’t stand it, but I’ve always decided, you know, if it doesn’t work, forget it and start planning the next experiment, and that’s always exciting.

I was writing poetry. But I found the theater such an exciting experience that one day I went home to try. I had one character say to the other guy, “Hey, man, what’s happening.” And the other guy said, “Nothing.” I sat there for twenty minutes and neither of my guys would talk. So 1 said to myself, “Well, that’s all right. After all, I’m a poet. I don’t have to be a playwright. To hell with writing plays. Let other people write plays.” I didn’t try to write a play for a number of years after that first experience.

It was like switching out the engines mid-flight. I remember the day we turned on this free service, had we probably gone on for about six more months, I think we might have died as a company. That was a defining moment and that was as late as 2013. I think every great company has at least three near-death experiences.

I tried for a Ph.D. scholarship to work with Cedric Mims, but was told to apply again later because he already had a "scholar" and would take only one student at a time. … The following week a job in the Department of Experimental Pathology at the Moredun was advertized in Nature. We sailed for Britain in early 1967, on a very slow and cheap ship.

Study broadly. Don’t specialize too early. Read history. Sooner or later, you’re going to have to specialize, but within the limits that you have to take obligatory courses to get a degree, keep your general education as broad as you can, because you never know what doors are going to open to new opportunities — ten, 15, 20 years down the road — because of changes in science and technology.

Oh, my granddad was ahead of his time. He was always in favor of education. My dad and mother were too, but Granddad was very aggressive in that. You know, as he used to say, “You’ve got to fill your head with new ideas so you can use them later to improve your own status and that of the neighborhood.”
