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.

I spent years trying to work out the secret of acting. I read all the books by the great teachers and got nowhere. They were so busy making it sound complex. I just couldn’t figure it out. Then one day my acting coach in LA told me to ‘think before you act’. It was so simple – when you are acting don’t just speak the words, but concentrate and think about what you are going to say all the time. It worked for me.

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.

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

It’s a gut thing. There’s no rhyme or reason to it.

I think acting your age is allowing other people to make decisions for you about how you should behave and what is age-appropriate. I encourage people to live and not be tied down with other people's expectations of what you should be doing. If you want to do something, go and do it. We overly worship the altar of youth. It's not good for our mental health. As a culture, we need to get better at seeing the beauty in aging and the beauty in things that are not young.

I once spent a summer doing a puppet show in kindergartens around the Shetland Islands.

Well, you have to learn to say no. Certain times you have to think, all right, line in the sand. It’s a gut thing. There’s no rhyme or reason to it. I’m going to do this Beckett Play in London with Daniel Radcliffe. He said this really interesting thing about how he feels that he’s lucky enough that when he chooses a part, that he only does something that he thinks he can bring something to. I think that’s really good, if you have that choice.

Try to be the same as everybody else.
