可持续发展不是一种选择，而是我们对下一代的责任。

Failure gave me an inner security that I had never attained by passing examinations. Failure taught me things about myself that I could have learned no other way. I discovered that I had a strong will, and more discipline than I had suspected; I also found out that I had friends whose value was truly above the price of rubies.

译文：势单力薄容易受到损害，人多势众则不容易被摧毁。

我从不相信失败。如果能享受过程，就没什么失败可言。
