The greatest glory in living lies not in never falling, but in rising every time we fall.
生活中最大的荣耀不在于从不跌倒，而在于每次跌倒后都能站起来。
Security is always excessive until it's not enough.
“唯一真正不朽的是人类的遗产。”
The end of history will be a very sad time. The struggle for recognition, the willingness to risk one's life for a purely abstract goal, the worldwide ideological struggle that called forth daring, courage, imagination, and idealism, will be replaced by economic calculation, the endless solving of technical problems, environmental concerns, and the satisfaction of sophisticated consumer demands.
