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。
The human heart, at whatever age, opens only to the heart that opens in return.
Never stop learning—the moment you do, you fall behind.
Quiet people have the loudest minds.
The only way to be free is to serve.
实现明天的唯一限制是我们今天的疑虑。
I'm not a hero; I'm a survivor.
"The dead are invisible, they are not absent."
