预言是人类唯一一项无法由重复练习而进步的技术。

I constantly see people rise in life who are not the smartest, sometimes not even the most diligent, but they are learning machines. They go to bed every night a little wiser than they were when they got up and boy does that help, particularly when you have a long run ahead of you.

正直不会遭遇祸患，谦和不会损害道义。
