Money is the only thing that separates the winners from the losers.

The measure of our success is not just in tons extracted, but in communities uplifted.

And as I am an honest puck,if we have unearned luck,now to's scape the serpent's tongue,we will make amends ere long,else the puck a liar call.

——在广州全国青年联合会演说，1923年10月21日

永远不要停止学习；当你认为自己无所不知的那天，就是你开始落后的那天。
