没有了目的，生活便郁闷无光。

"History is not the past—it is the method we have evolved of organizing our ignorance of the past."

应对不自由世界的唯一方法是变得如此绝对自由，以至于你的存在本身就是一种反叛。

Art is not what you see, but what you make others see.

译文：假如你命中富贵荣华，也要常常有不得意的想法；假如你碰到境遇顺利，也要常常有不如意的念头；假如眼前的你吃穿丰足，也要保持节俭不忘贫困；假如别人都很喜欢你，也要常常怀着谨慎的想法；假如你家世名望都很高，也要常怀着谦虚卑下之心；假如你的学问非常高深，也要提醒自己掌握的还不够多。

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

Science is not a boy's game, it's not a girl's game. It's everyone's game. It's about where we are and where we're going.
