Robinson Crusoe’s famous aphorisms are as follows:

1. All things in the world are most valuable only if they are useful. If you accumulate too much of anything, you should give it away. Others; what we can enjoy is at most the part that can be used by us, and it is useless to have more.

2. In life, people often cannot truly appreciate the benefits of the original environment without seeing a worse environment with their own eyes; without falling into a desperate situation, they will not truly cherish what they have received. thing.

3. The reason why they cannot enjoy God’s gifts comfortably is because they are always hoping and coveting things that they have not yet obtained.

4. When you start to do something, it would be really stupid if you don't calculate in advance how much it will cost, and if you don't make a correct estimate of your own strength in advance.

5. Most people often have a common problem, that is, they are often dissatisfied with the living environment that God and nature have arranged for them. In my opinion, at least half of their sufferings are caused by this common disease.

6. We ordinary people cannot understand the superiority of the original environment until we see the harsh environment with our own eyes; we cannot appreciate the things we originally enjoyed until we are at the end of our rope.

7. We always feel that something is missing and are not satisfied because we lack gratitude for what we have already received.
