"It is worth living for, to find out what is true."

The fundamental impulse that sets and keeps the capitalist engine in motion comes from the new consumers' goods, the new methods of production or transportation, the new markets, the new forms of industrial organization that capitalist enterprise creates.

Sustainability isn't a cost center - it's the ultimate competitive advantage.

Keep the faith.

译文：求全责备之心，可以用在自我的修身养性上，不能用在待人接物上；知足常乐的心态，可以用在各种处境的时候，不能用在读书学习上。赏析：严以律己，宽以待人，是做人的根本，是远离祸患的根本。读书学习，我们不能安于现状，要有进取精神。在为人处世时，我们索取无度，贪得无厌，就会自食恶果。

"You have to work hard to get to the top, but you have to work even harder to stay there."
