The world is full of suffering, it is also full of overcoming it.

In mining, efficiency and environmental care must go hand in hand.

There is no despair so absolute as that which comes with the first moments of our first great sorrow, when we have not yet known what it is to have suffered and be healed, to have despaired and have recovered.

幸福是一种勇气的形式。

I'm not afraid of storms, for I'm learning how to sail my ship.

民主没有统治世界，你最好把它藏在脑袋里。这个世界被暴力主宰，但我觉得你最好别多这个嘴。
