时间
我们这一生的财富都是从时间里面挖出来的。我们的精神财富和物质财富都是从时间里面挖出来的。我们的时间可以花在很多很多地方，但是最值得花时间的地方是自学。
时间是终极的生产资料。
推论1：用“时间成本”筛选我们要做的事。
推论2：培养长期观念，想办法做必须长期投入才能越做越好的生产。
知识
我们应该更多的去学习知识，我们需要去学生产知识、销售知识、投资知识。因为我们的物质财富主要来自三类活动：生产、销售、投资。生产包括发现、制作、交易商品或服务。销售的好处：距离制作足够近、理解真正的需求、理解真正的竞争、收入可以无上限。
钱
钱是一种社会账簿，你给社会提供了价值，社会就会让你得到钱——作为打给你的欠条。等到你需要什么的时候，就可以拿这些欠条去社会上兑换相应的商品或服务。
钱是最灵活的生产资料。
因为，钱可以用来购买其他的生产资料——物资、人力、信息，甚至可以间接购买到终极生产资料——时间。比如，我们可以用钱购买提升效率的工具，可以购买家政服务、可以打滴滴来节约自己的时间。除此之外，钱，还能生钱。通过把钱投资/借贷出去，充当其他人的生产资料，在对方使用得到的情况下，我们就让钱生产出了更多的钱。由此，我们有充分的理由想尽办法善用好自己的钱。
Time
The wealth of our lives is all dug out from time. Our spiritual and material wealth are both derived from time. We can spend our time in many different ways, but the most worthy investment of time is self-learning.
Time is the ultimate means of production.
Inference 1: Use “time cost” to filter the things we choose to do.
Inference 2: Cultivate a long-term perspective and find ways to engage in activities that require long-term investment in order to continuously improve production.
Knowledge
We should focus on learning more knowledge. We need to learn about production, sales, and investment knowledge because our material wealth primarily comes from three activities: production, sales, and investment. Production involves discovering, creating, and trading goods or services. The benefits of sales include being close to the production process, understanding real needs, understanding real competition, and having unlimited income potential.
Money
Money is a social ledger. When you provide value to society, society will give you money as a form of IOU. When you need something, you can use these IOUs to exchange for corresponding goods or services in society.
Money is the most flexible means of production.
Because money can be used to purchase other means of production - materials, labor, information, and even indirectly purchase the ultimate means of production - time. For example, we can use money to buy efficient tools, hire domestic services, or take a ride-hailing service to save our own time. Additionally, money can generate more money. By investing or lending money to others and allowing them to use it, we enable money to produce more money for us. Therefore, we have every reason to find ways to make good use of our money.
