It was a very simple thing. It was a church camp, I think. I was there about two or three days, very young, and I just remember some counselor telling us that reputation is what people think you are, and your character is what you are. So if you have a bad reputation, you might as well have a bad character, and it pays to have a good reputation and a good character.

And I never forgot what he said, Bill Clinton. He looked at me, and he said, “You know, Leon, you can be the greatest OMB director in the history of the world, but nobody’s going to remember you if the White House has fallen apart!” I never forgot that.

Harold Prince went to see it and he wrote me a letter saying don’t be discouraged about this because actually there’s some quite good songs in here. But he also said something which stayed with me all my life, which is that you can’t listen to a musical if you can’t look at it, by which he was actually saying that the designs for Jeeves were absolutely hideous.

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

So I got this new attitude.  Now that I am burned out and I’ll never accomplish anything, I’ve got this nice position at the university teaching classes which I rather enjoy, and just like I read the Arabian Nights for pleasure, I’m going to play with physics, whenever I want to, without worrying about any importance whatsoever.

Then I had another thought: Physics disgusts me a little bit now, but I used to enjoy doing physics.  Why did I enjoy it?  I used to play with it.  I used to do whatever I felt like doing—it didn’t have to do with whether it was important for the development of nuclear physics, but whether it was interesting and amusing for me to play with.

I had nothing to do, so I start to figure out the motion of the rotating plate.  I discover that when the angle is very slight, the medallion rotates twice as fast as the wobble rate—two to one.  It came out of a complicated equation!  Then I thought, “Is there some way I can see in a more fundamental way, by looking at the forces or the dynamics, why it’s two to one?”

So I find that teaching and the students keep life going, and I would never accept any position in which somebody has invented a happy solution for me where I don’t have to teach.  Never.

It's made me a very happy man ever since.

I don’t believe I can really do without teaching.  The reason is, I have to have something so that when I don’t have any ideas and I’m not getting anywhere I can say to myself, “At least I’m living; at least I’m doing something; I’m making some contribution”—it’s just psychological.
