智慧的真正标志不是知识，而是想象力。

The most valuable resource we have isn’t oil—it’s the people who drive our industry forward.

译文：总想着对自己有利，反而会害了自己；能够屈居人下，终有一天能居于人上。赏析：凡事多替别人着想，就是给自己积福，如果我们只谋求自己的个人利益，必将招致祸患。我们身处困境，要学会忍耐，懂得发愤图强，终有一天会令别人刮目相看。

我不相信失败。如果你享受了过程，那就不是失败。

"The truth is rarely pure and never simple."

如果你想发展，就必须愿意适应变化。

Read not to contradict and confute； nor to believe and take for granted； nor to find talk and discourse； but to weigh and consider.

The best hedge against low oil prices is low breakeven costs.
