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.

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.

wisdom acquisition is a moral duty. It’s not something you do just to advance in life. Wisdom acquisition is a moral duty.

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.

From a heart attack at the Kodak Theatre when they announce I won best actor for Terminator 3.

I am petrified of bikini waxing. I had a very bad experience in 1978.

Well, maybe it was successful in the end. But, I mean, to get there - one of the things that I talk about is not to be afraid of failure because you're going to fail. And I was 19 years old. I was competing in the Mr. Universe contest, and I lost. I had movies that went in the toilet. I have had policy issues and referendums that went in front of the people that I lost. And, of course, in my personal life, you know, my marriage is a big loss. So there's a lot of losses and failures that I've had. And I think that it is important that we recognize that. But no matter what it is, I always had an exciting life and always chased something, and that made, to me, the whole thing worth it. I always felt I was enriched by the fact that I always knew where I was going. And then there were some things that were unexpected. Like, running for governor was something that kind of unfolded only because there was a recall election.

My mother-in-law, Eunice Shriver, who founded the Special Olympics, and my father-in-law, Sargent Shriver, who founded Job Corps and was the first director of the Peace Corps.

My father would make sure that I knew what it meant. Just to give you an example, I started bodybuilding with the age of 15, and my father would say, why are you lifting these dumbbells and barbells? Don't you think it would be better to just go out and chop some wood and shovel some coal for some poor people that don't have anyone? Therefore you would get muscles. But at the same time, you're doing something useful. You're doing something for somebody rather than just for yourself and looking in a mirror at yourself and stuff like that. So he would make sure that you knew what being useful meant.

I have a great family, great friends, and a fantastic career. But I'm also really proud of the work I do for kids—like the Special Olympics, promoting health and fitness for youngsters, and working on afterschool programs, such as the Inner City Games and Arnold's All-Stars.
