我对黑暗感兴趣。如果你不走进黑暗，你永远看不到光明。

The biggest risk is not taking any risk... In a world that's changing really quickly, the only strategy that is guaranteed to fail is not taking risks.

我从十五岁开始致力于学习，三十岁便能自立于社会了，四十岁对各种事理不再迷惑不解，五十岁懂得了自然界的规律，六十岁对听到的事情能领会贯通，并能辨别是非真伪，七十岁时做事能随心所欲，但又不会超出礼法的规范。

I've never been a person that has been like, 'I want to be a role model.' But then you realize you are, and you have to be careful with what you say and do.

Every problem in mathematics is a puzzle waiting to be solved, and the joy is in the solving.
