Economics is the study of how societies use scarce resources to produce valuable goods and services and distribute them among different individuals. If we think about the definitions, we find two key ideas that run through all of economics:

I'm not a role model. I'm just trying to be myself.

唯一值得写的就是人类内心与自我的冲突。

默记所学的东西，坚持学习而不厌烦，教诲别人不知疲倦。

A story is a way of making the invisible visible.
