我不让任何人定义我。

Success is not final, failure is not fatal: it is the courage to continue that counts.

数学的乐趣在于发现的旅程，而不仅仅是目的地。

质量不是流行语；它是一种生活方式。

不断学习的人，人生才会不断升华。

从近处看，生活是悲剧；从远处看，生活是喜剧。

Quality should never be compromised, even when pushing for efficiency.

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.
