学习数学的唯一方法就是做数学。

Don't fight a battle if you don't gain anything by winning.

Pros are just amateurs who know how to gracefully recover from their mistakes.

Efficiency without ethics is short-term success.

你做得越多，学到的就越多。你学到的越多，你能做的就越多。

写作是我向自己解释自己生活的唯一方式。

如果你想走得快，独自前行；如果你想走得远，结伴同行。

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