可持续林业不是一种选择；它是一种义务。

The purpose of life is not to be happy. It is to be useful, to be honorable, to be compassionate, to have it make some difference that you have lived and lived well.

Literature is the art of making the invisible visible.

我不相信幸福的结局。我相信真实的结局。

我不是英雄，我不是反派，我只是一个人。

Change starts with awareness, but it requires action to make a real difference.
