The secret of life is not just to survive, but to thrive with passion, compassion, humor, and style.

I went to the woods because I wanted to live deliberately,I wanted to live deep and suck out all the marrow of life, To put to rout all that was not life, and not when I had come to die, Discover that I had not lived.

生命的意义在于追求真理。

世界并不友善，但它是正确的。

建模的艺术在于忽略正确的东西。
