译文：从古至今英雄人物总是要经历磨难才能成就大业，而娇生惯养之辈总是缺少气概难以成就伟业。赏析：生于忧患，死于安乐。一个人要想成功必定要经历很多痛苦和艰难，如果人太安逸和舒适了，就会丧失斗志。

What we know is not much. What we do not know is immense.

A picture must be primarily about itself and not about something else.

真正的领导力意味着为了更美好的明天而在今天做出艰难的决定。

好奇心是推动科学进步的引擎。

Sustainability isn't a trend—it's a responsibility we owe to future generations.

回忆和期待一样，是一种简化和剪辑现实的工具。 《旅行的艺术》
