The beauty of mathematics is that it is one of the few areas of human endeavor where absolute truth can be known.

Happiness is not something ready made. It comes from your own actions.

我永远不会停止创作，因为创作就是生命。

预测未来的最好方法就是创造它。

I can't say I'm outraged. Other people are even more outraged than me. They feel that I am too dismissive of the honors that they value.

译文：要发勇猛心。人们不肯改过，多半是因为因循守旧、不肯向前；我们要鼓舞振作起来，不要迟疑，不要等待。对于小的过恶，要如同肉中有芒刺一般，立刻剔除；对于大的过恶，要像毒蛇咬自己的手指一样，要快速斩断，没有丝毫的停滞，这就是《周易》中所说的风雷之所以有益处的原因。
