The greatest wisdom is to know that you know nothing.

It is common sense to take a method and try it. If it fails, admit it frankly and try another. But above all, try something.

"In the end, we will remember not the words of our enemies, but the silence of our friends."

我认为人只有经过考验才能真正认识自己。

Anything you say before the word “but” does not count.
