...The history of exploration across nations and across time is not one where nations said, 'Let's explore because it's fun.' It was, 'Let's explore so that we can claim lands for our country, so that we can open up new trade routes; let's explore so we can become more powerful.

...Exploration is really the essence of the human spirit.

...I could do exploration in this particular career field, and it was a goal that, even if I didn't reach it, it was so high it seemed almost impossible, but even if I didn't reach it, I would still have a good time and a very satisfying career.

...If I wasn't doing this kind of exploration, I'd like to be doing some other kind of exploration. It might be more risky, or less risky, but, in the business of exploration, risk is part of the territory.

...Exploration is the engine that drives innovation. Innovation drives economic growth. So let's all go exploring.
