庆祝你的成功。在失败中找到幽默。不要把自己看得太严肃。放松，你周围的人也会放松。享受乐趣。总是表现出热情。

Innovation in the gas sector must balance immediate needs with long-term sustainability goals.

Comedy is the ultimate revenge against tragedy.

You must be filled with expectancy. You must be awash in hope.

Natural experiments are a powerful tool for understanding causal relationships in the real world.

今天就改变你的生活。不要赌未来，现在就行动，不要拖延。

真正的诗歌源于痛苦和欢乐。
