A miner's skill and dedication are just as valuable as the coal they bring to the surface.

释义：在遭受挫折、忍受屈辱的艰难时刻，一定要咬紧牙关，激励自己坚定志向。积蓄内心的力量，让自己的意志愈发坚韧，使志向得以长远发展，绝不因一时困境而退缩放弃。

希望存在于任何黑暗中。

"The soul becomes dyed with the color of its thoughts."

"The worst lies are the ones we tell ourselves."

Consciousness is the cutting edge of the struggle for existence.
