宇宙星辰

微尘之上，四季更迭，昼夜交替。我们是生物，也是人类。即使一切无意义，也愿我们的文明璀璨、科技进步，每个个体都可发出自己的荧光

Pale Blue Dot — Carl Sagan

Look again at that dot. That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every “superstar,” every “supreme leader,” every saint and sinner in the history of our species lived there-on a mote of dust suspended in a sunbeam.

— Carl Sagan, Pale Blue Dot: A Vision of the Human Future in Space

那些必需但又难以改进的事 — 刘俏

“生命中真正重要的不是你遭遇了什么，而是你记住了哪些事，又是如何铭记的。” 去做那些必需但又难以改进的事情。这个过程中，你可以看到自己、认识自己、点燃自己。世间不论是康庄大道还是旁门左道，一定是熙熙攘攘、人流如织，你的贡献注定有限；是曲折小路上那些必需但又难以改进的事能够给自己、社会和这个时代带来更大的改变，它们也是你刻骨铭心最终会记住的。

2020届的毕业同学们，从这个拐角出发，请记住在未来的岁月里——不管你是一帆风顺还是在经受磨难，不管是身处庙堂还是远在江湖——不时停下问问自己，“哪些是必需但又难以改进的事？”（What is essential and yet hard to improve?）“我是不是正在做必需但又难以改进的事？”(Am I working on what is essential and yet hard to improve?)如此，我相信，即使是最平凡的人生，也将会有不同寻常的意义。
