It's just, I would say, faith. I had very clear visions of me being a champion. When I saw this picture of Reg Park on a cover, standing there like - as Hercules, from the Hercules movies, I looked at that, and then I looked at the inside and I read the story, and I immediately started creating visions of me standing there on the pedestal at the Mr. Universe contest and me being Hercules and me doing movies and so on. And that created such unbelievable drive and such unbelievable will and discipline, that there was absolutely no stopping me. I mean, I went to the gym two hours every day lifting weights. When I came home afterwards, I lifted an extra hour and a half and did bodybuilding training, and it was just relentless.

Well, I hate the word, but it’s true that something sometimes visits and other times doesn’t. I wish I felt otherwise, but I feel as though there has to be some catalyst, some inspiration. All of a sudden there’s a phrase in your head. Where does that thing come from? I don’t know, and because I don’t know, I don’t know how to have more of them.

We didn’t research the product. We didn’t launch a focus group or field a study. We had an idea, and we acted. The results informed our thinking.

I think it’s very different in what I do. Edison’s work was so much tinkering and trying it out and empirical testing. So much of my work is writing. I don’t know what you call the writing, it’s true that the actual inspiration, say for writing an essay, the outlining of it is probably a 15-minute to half-hour procedure, then you may spend about 20 hours writing it. But the writing isn’t perspiration in the same sense. It’s not inspiration, but it’s something in between. Any profession has a vast amount of tedium attached to it. There’s no sense not admitting it. If you’re passionate about it, tedium can be — not exactly a joy — but can be perfectly tolerable. The tedium of a pianist is 10 hours of practice a day or whatever, not all of which is inspirational. The tedium of an experimental scientist is calibrating the machines and doing it over and over again. The tedium of a paleontologist is poring over a microscope, or using a dental pick to chip away the sand grains from the fossil, or looking at the statistical figures in the columns of a computer printout. Every profession has massive tedium, that’s certainly true. You cannot be a successful professional (without it). But I think if you’re committed to it, as they say, it goes with the territory. It’s part of the work.

I wrote a little book called Screening History , in which I go in great detail into the movies that affected me growing up. This was in the years of puberty, and so on. The Prince and the Pauper , based on Mark Twain’s novel with the Mauch twins in it. All of the propaganda films I loved, because they were political.

I remember being present when a Jesuit priest in Rome asked Tennessee Williams, “How do you write a play?” and Tennessee said, “Well, I start with a sentence.” Well, I start with a sentence, and that’s how you write a book.
