Der bestirnte Himmel über mir und das moralische Gesetz in mir.
我头上的星空和我心中的道德律。
人生就像一首歌，有高潮也有低谷。
The greatest happiness of the thinking man is to have fathomed the fathomable, and to quietly revere the unfathomable.
It's not having what you want, it's wanting what you've got.
Never stop learning; the world is constantly evolving, and so should we.
