Failure is just a stepping stone to success.

The world is not run from where he thinks. Not from castle walls, but from countinghouses, not by the call of the bugle but by the click of the abacus, not by the grate and click of the broadsword but by the scrape of the pen.

最好的数学不仅仅是逻辑的；它是直观和创造性的，将严谨与想象力结合在一起。

我会用尽我所有的工具，上帝赐予我的能力，并以此创造最好的生活。
