不要为变老而遗憾。这是许多人求之不得的特权。

我不等待机会，我创造机会。

The law, in its majestic equality, forbids the rich as well as the poor to sleep under bridges, to beg in the streets, and to steal bread.

I think it matters whether someone has a good heart.

活着的当下就是一切。

Every equation we write is a small step towards understanding the cosmos, but the journey is infinite.

如果退一步能进两步，我绝不害怕后退。
