Mathematics is not just about numbers, equations, computations, or algorithms: it is about understanding.

成功不在于完美，而在于坚持。

一个灰色的回忆，怎能抗衡现在的生动与自由。

The heart is a strange thing. It can be broken and still keep beating.

The purpose of literature is to disturb the comfortable and comfort the disturbed.

我不让消极情绪把我打倒。我会超越它。
