I often repeat to them something that — not my mentor, but a senior scientist at the NIH — said to me once. We were having lunch together. I was despondent, despondent because nothing had worked. I had been there a year. And this guy said to me, “Look,” he said, “do you know the difference, Bob, between an average scientist and a world class scientist?” I said no. He said, “Here’s what it is.” He said, “For the average scientist, maybe one percent of their experiments work. But for the world class guy, the world beater, it could be as high as one-and-a-half or two percent.” And then that really stuck with me because it’s really true.

Right, I went back as a mature student to art school, and I was advised to use my train journeys and commutes, or to just take time in the morning before work to sit down and write something. That was, I think, the beginnings of understanding what it meant to have a writing practice.

Run toward the hardest problems. At the time, I didn’t fully understand what that meant.  But over time, I realized this was the best advice I ever received. Hard problems teach you what you're capable of.  Fast forward a bit … 12 years ago, I got a chance to put that lesson to the test. I had the opportunity to become CEO of AMD. AMD had enormous potential, but the company had been through some tough years. Some of my mentors thought taking the job was risky. But for me, this was my dream job. This was what I’d been training for all those years. The opportunity to work at the bleeding edge of technology on problems that really mattered. The first thing we had to figure out was what we wante

When I first met Sergeant Jackson I had grown a mustache and had taken up the affectation of smoking cigars, because I thought this made me look, you know, quite dashing and much older than my 22 years, or what have you. And the first thing that Sergeant Jackson did after I asked him to, in essence, take the insignia off, you know, just tell me straight up what I could do to improve my performance. And he told me, he said, “Well, the first thing, shave off that ridiculous mustache, and quite smoking the cigars — because you look absurd — and be yourself.” And I don’t think I ever forgot that. I don’t think I ever tried an affectation after that point in my life.

Well, what's very interesting is that those people read our opinions which can be, at moments, rather animated. An animated exchange in writing among the justices. And many people who read our opinions think we have to be at each other's necks constantly. It's interesting we're not. When we're talking about cases at our conference it's generally a conversation. It's really a talk about what our perspectives are and why we have reached the conclusions we've reached.
