The task of economics is not only to interpret phenomena, but also to provide practical advice and policies for society.

A good person will follow the rules, a great person will follow himself.

譯文：人的一生能有多少個今天呢，今天不去做事實在是可惜了。賞析：今日事今日畢，我們要活在當下，每天都要做些有意義的事情。明天有明天的事情，萬事都要等到明天去做，就會蹉跎光陰。

The context is the work.

愛是感官的詩歌。
