有时最简单的旋律承载着最深刻的情感。

The good life is a process, not a state of being. It is a direction, not a destination.

"You can't go back and change the beginning, but you can start where you are and change the ending."

I don't think about limitations. I just think about possibilities.

数学中最深刻的发现往往来自最简单的观察。
