I always have, in my expeditions, people who are academically far cleverer than I am, and even technically, far more competent. So if you want to lead an expedition, in a sense, you’ve got to keep ahead of them. These bright, competent characters you have with you who are marvelous to have on the expedition. And I’ve always found you can do that by, each night, when you go to bed, just let your mind dwell on the likely things that may happen next day, and think out carefully the sort of decisions that might be necessary to make in order to have the program carried through. So next day, when something happens, you’re the one that’s thought about it and you’re the one who has the ideas.

I wanted to be an Olympic champion and I didn't care about the goings-on around me. In my heart and with all of my soul I was ready, willing and I was very able. I had a deadly sense of self-belief. I'd go to another level and say I had a deadly sense of self-conviction where you can say whatever you want, you can do whatever you want but you're not going to touch me.

I find that you’re a completely different person as a maker than you are as a listener. That’s one of the reasons I so often leave the studio to listen to things. A lot of people never leave the studio when they’re making something, so they’re always in that maker mode, screwdriving things in - adding, adding, adding. Because it seems like the right thing to be doing in that room. But it’s when you come out that you start to hear what you like.

But I couldn’t let myself feel that way until it was all right to. And that’s part of the surgical mind too, addressing what you need to, and you know you can do, and postponing how you feel about it, thinking only of the patient and what you need to do.

One cannot overemphasize the importance of observation and a full assessment — the failure to do so leads to some of the greatest mistakes, not only in war but also in business and government. A full assessment is critical. To properly manage any business situation, you need to perform a full and complete assessment of it. In business, you have to understand your competitors, their distribution, their economics, their innovations, and their strengths and weaknesses. You also need to understand customers and their changing preferences, along with your own costs, your people and their skills.
