I’m still astonished that somebody would offer me a job and pay me to do what I wanted to do. And to this day, that’s been the astonishment of my life, and delight of my life, and the wonder of my life, and the puzzlement that anybody would be so stupid as to be willing to do that. I hear all these success stories of people, these captains of industry, these forgers of the world, and empire builders and so on. And they talk about all the money they’ve made and become presidents and all that, and I thought, jeez, but look at me. When I was offered a chance to be head of studios I wouldn’t take it. I like to work with the tools of my trade. The tools of my trade is a lot of paper and a pencil, and that’s all it is.

The highest form that civilization can reach is a seamless web of deserved trust. Not much procedure, just totally reliable people correctly trusting one another. That's the way an operating room works at the Mayo Clinic. If a bunch of lawyers were to introduce a lot of process, the patients would all die. So never forget, when you're a lawyer, that you may be rewarded for selling this stuff, but you don't have to buy it. In your own life, what you want is a seamless web of deserved trust. And if your proposed marriage contract has forty-seven pages, my suggestion is you not enter.

I don’t think of it as research. I read for interest and enjoyment, and when I cease to enjoy it I stop. I didn’t research quantum mechanics but I was fascinated by the mystery that lies in the foundation of the observable world, of which the most familiar example is the wave/particle duality of light. I thought it was a good metaphor for human personality. The language of espionage lends itself to this duality—think of the double agent.

I’ve had a long career as a writer, and a good one, in good company. Here at the end of it, I don’t want to watch American literature get sold down the river. We who live by writing and publishing want and should demand our fair share of the proceeds; but the name of our beautiful reward isn’t profit. Its name is freedom.

I just like to get to the start line knowing there was nothing else I could have done, that there wasn't a single session I didn't give 100 per cent. The physical certainty means you can relax mentally and let the performance come.

The six Olympic gold medals, because at school I was never great at sport. When I look back on my career I think, how on Earth did that happen?

Jason Queally, a former teammate. He is older than me and was Olympic champion in Sydney. The way he mentored me, even though he knew I would be a rival, was amazing.

Those lactate sessions were the worst. I'd be in a lab on a turbo trainer and I'd do four 30-second efforts at 100% effort. It sounds so innocuous but the difference between 99% and 100% is huge. You can finish at 99% and you'll be hurting but if you push a tiny bit more – and that's the bit that makes the difference to your training – your legs just grind to a halt. It's like your engine is seizing up. My coach would unclip my feet and pull my leg over the saddle so I could just slide off onto a mat and curl up in a ball.

The London terror attack on 7/7 in 2005. I was in London the day before for the Olympic bid. When we won I thought, “I should stay over – it will be a great party tonight.” But I decided to go back to Manchester for training. Bombs went off on what would have been my route to the station.

Scotland’s rugby captain. My hero Gavin Hastings was captain when he came to our school for a training session when I was 10 or 11. I met him and was blown away.
