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.

I decided that my attention would be in the dining room. I haven’t cooked in 28 years at Chez Panisse. ... I didn’t intend to be out of the kitchen. ... Now I’m in a different world and I contribute to the collaboration of the kitchen and I’m always working with a group of colleagues who inspire me, but I really miss being actually in the solving of the performance, that effort to really come up with dishes that are delicious and right.

We were training 12 to 15 times a week, 50 weeks of the year. I think sometimes people see you compete at the Paralympics or other amazing places around the world and think that is what you do all the time. There is an element of that, but a lot of it is just really boring and repetitive. The vast majority of your time as an athlete is spent on the road or in the gym.

I was living in survival mode when I was young. I'm now trying to teach the people to live in a mentality that they can be whatever they want to be even though the situation around them is hopeless.

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.

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.

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.

Max Levy, a German sprint cyclist who came second behind me a lot.

I don't enjoy it but I know that I have got to live with [myself] if I'm not going to give it 100 per cent. The key thing is getting to the start line and knowing that I couldn't have done any more, that I didn't back off. You accept the pain, because if you didn't there would always be that element of doubt.

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?
