The chief enemy of creativity is 'good' sense.

When you focus on doing what's right rather than what's easy, success follows naturally.

最好的发现来自于提出正确的问题。

富家子弟因求官位而倾家荡产，贪污的官吏因贪财而失职守。

You are never too old to set another goal or to dream a new dream.

The heart is a lonely hunter.

"The only thing to do with good advice is to pass it on. It is never of any use to oneself."
