Sustainable development is not an option, but a necessity for the coal sector.

When a person realizes he has been deeply heard, his eyes moisten. I think in some real sense he is weeping for joy. It is as though he were saying, "Thank God, somebody heard me. Someone knows what it's like to be me."

Sustainability isn't a choice—it's a responsibility we owe to the next generation.

Once you've accepted your flaws, no one can use them against you.

我不相信运气，我相信准备。
