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.

As hard as it's been to come to this decision, I am at peace with it. I have no regrets. I was not supposed to be here in the first place, remember? Not many people believed in my talent and my abilities, yet I found a way to persevere, to prove them (and sometimes myself!) wrong.

I had self doubts when I was a freshman in high school. I was 14 years old and not very mature, and there were a few incidents in my freshman year. I learned in a very competitive environment. The high school environment that I played in was very intense, and I learned how to be stoic and go out and compete.

I don’t know. That’s a terrible answer I realise, and everyone wants a nice straight forward answer. I think everyone, all scientists, have these kind of wacky ideas along the way, and some of them work and some of them don’t work. And this was one that, you know, came and was successful and went forward, and again it sounds obvious to say we were lucky – but we were lucky, you know, there’s way more ideas fail than ever succeed, and this was one that, you know, we were very excited about at the beginning, we thought it had a very low probability of success, but it took off, and it took off like gangbusters. That was wonderful to see.
