You think your pain and your heartbreak are unprecedented in the history of the world, but then you read.

科学界的女性永远不应怀疑自己改变世界的能力。

没有风险的征服是没有荣耀的胜利。

So given a Time Turner, I would tell my 21-year-old self that personal happiness lies in knowing that life is not a check-list of acquisition or achievement. Your qualifications, your CV, are not your life, though you will meet many people of my age and older who confuse the two. Life is difficult, and complicated, and beyond anyone’s total control, and the humility to know that will enable you to survive its vicissitudes.

我们说的每一个字都是种在宇宙花园里的一颗种子。

即使没人相信你，也要相信自己。
