I think the Lewis and Clark Expedition was the greatest undertaking in American History. I think landing a man on the moon pales next to it.
No one will pay you for planning an expedition at first: you have to work in pubs at weekends so you can pay the gas bills. I joined the Territorial Army, which paid me when I turned up to drill nights, and so did my wife.
Adventure books are my personal favorites. 'The Endurance,' a story about Ernest Shackleton's legendary Antarctica expedition, or 'Into Thin Air,' Jon Krakauer's personal account of the 1996 disaster on Mt Everest, are two notables.
Good planning is important. I've also regarded a sense of humor as one of the most important things on a big expedition. When you're in a difficult or dangerous situation, or when you're depressed about the chances of success, someone who can make you laugh eases the tension.
We were in the Arabian Desert for nine months. And I was having the time of my life. It could have been an archeological expedition, a military expedition.
What you do on a dinosaur expedition is you hike and look at the ground. You find bones sticking out of the dirt and, once you see something, you dig.
Writing a novel is not merely going on a shopping expedition across the border to an unreal land: it is hours and years spent in the factories, the streets, the cathedrals of the imagination.
A life lesson for me is, how do you muster the courage to take on a new risk? Whether it's starting up a business or taking on a new project or expedition. I think the risks that we take are all relative to the risk-taker.
I've always liked adventure television. Pre-'Survivor,' I did a series on cable called 'Eco-Challenge,' an adventure race with experts mainly, and here we have 'Expedition Impossible.' I like the outdoors and I like doing something fresh for television you haven't seen before.
A review of summit day photographs will show that I was clothed in the latest, highest quality, high altitude gear, comparable, if not better, than that worn by the other members of our expedition.
