最大的风险是不冒险。

A mathematician's best work often comes from seeing connections where others see none.

人无远虑，必有近忧。如果做事没有计划，毫无思想准备，就不能从容应付突如其来的事情。

The unity of mathematics is not imposed but discovered.

The only way to do great work is to love what you do.

静坐的时候才知道平日的心浮气躁，独自呆着不说话才知道平日言语暴躁多话。反省行为才知道平日心情忙乱，闭门拒绝客友才知平日交友泛滥。少欲望才知道平日多病。近人情才知道平日待人处事的苛刻。
