我不想画那些像模特一样坐在那里的人。我想画真实的人。

You cannot get through a single day without having an impact on the world around you. What you do makes a difference, and you have to decide what kind of difference you want to make.

The best steel isn't made in furnaces; it's forged through teamwork and shared purpose.

"We are all in the gutter, but some of us are looking at the stars."

看着容易，要学会就很难；千万不要把容易得到的东西看得普通，就不知道珍惜。

真相并不总是美丽的，但对真相的追求是。

定理是永恒的；它们的证明是短暂的。
