安全不仅仅是一个优先事项，它是必须融入我们所做一切的核心价值观。

Every ton of coal we extract must create maximum value with minimum environmental impact.

The artist must create his own mythology.

It was like when you make a move in chess and just as you take your finger off the piece, you see the mistake you’ve made, and there’s this panic because you don’t know yet the scale of disaster you’ve left yourself open to.

The environment shapes behavior through the mechanism of reinforcement.

我们被要求的不是成功，而是忠诚。
