The beauty of mathematics lies in its ability to simplify complex phenomena.

We tend to overestimate what we can do in a day， and underestimate what we can achieve in a decade. Miraculous things can be accomplished if you give it ten years. A long game will compound small gains to overcome even big mistakes.

I try to leave every place a little better than I found it.

快乐在于旅程，而不仅仅是目的地。

我们都在互相陪伴着回家。
