To be a writer is to sit down at one's desk in the chill portion of every day, and to write; not waiting for the little jet of the blue flame of genius to start from the breastbone.

有志之士珍惜每一年的光阴；贤德之人，珍惜每一天的光阴；而圣人则会珍惜每一寸的光阴。

数学家的工作永远不会完成；总有新的问题需要探索，新的谜团需要揭开。

It is a fine thing to have ability,but the ability to discover ability in others is the true test.

最好的投资是投资于能够创造价值的人。
