It's amazing how willpower can build walls. - Yann Martel

The tennis challenger starts strong but soon loses confidence in his playing. The champion racks up the games. But in the final set, when the challenger has nothing left to lose, he becomes relaxed again, insouciant, daring. Suddenly he's playing like the devil and the champion must work hard to get those last points.

My gratitude to him is as boundless as the Pacific ocean.

When your own life is threatened, your sense of empathy is blunted by a terrible, selfish hunger for survival.
