Expeditions are escapism. The stuff that we're normally concerned about just doesn't matter out there. Tax returns, gas bill, none of it. Life becomes very simple, it's about moving in a certain direction - north if you're going north - staying warm and not getting eaten. That's it.
Environmental scientists in Canada said it was impossible for me to get to the Pole in 2004... I said 'no,' it's still OK, and I can still get there, and I did.
My Antarctic expedition is just about doable, just feasible and that's what is exciting to me. If I knew it was possible, if I knew I could do it without too much bother, I wouldn't be interested.
