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:
经济学特别是宏观经济学中说的投资是耐用资本品如厂房设备的生产，而平常说的“投资”是指购买资产如股票，这和经济学中的投资不同，为了区分，这种投资被称为金融投资。
在以情动人前，你自己要先被打动。在你催人泪下前，你自己要热泪盈眶。在你以理服人前，你自己要坚信不疑。
These walls are funny.First you hate them,then you get used to them;Enough time passes,gets so you depend on them.That's institutionalized.
最好的想法往往来自最意想不到的地方。
小说是一面沿着大路携带的镜子。
