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:

我喜欢看起来漂亮，但我总是把舒适放在时尚之上。

成衣业的成功源于理解设计的艺术和生产的科学。

领导力在于做出艰难的决定并坚持到底。
