Outside of my family, I was always inspired by true heroic stories of leadership and survival. For example, the story of the Shackleton expedition, when their ship became lodged in the Antarctic ice pack while exploring.


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 now back at Smith Landing, and fired with a desire to make another Buffalo expedition on which we should have ampler time and cover more than a mere corner of the range.

The constitution vests the power of declaring war in Congress; therefore no offensive expedition of importance can be undertaken until after they shall have deliberated upon the subject and authorized such a measure.

As soon as the news of the Cabot voyages reached the King of Portugal he arranged to send an expedition of discovery to the far north-west, perhaps to find a northern sea route to Eastern Asia.

An insuperable obstacle to rapid transit in Africa is the want of carriers, and as speed was the main object of the Expedition under my command, my duty was to lessen this difficulty as much as possible.

Supplying fuel for a Mars expedition from the lunar surface is often suggested, but it's hard to make it pay off - Moon bases are expensive, and just buying more rockets to launch fuel from Earth is relatively cheap.
