Daniel Defoe's famous saying:

1. It can be seen that we ordinary people cannot understand the benefits of the original environment unless we see a worse environment with our own eyes; To the point where you don’t know how to value what you originally enjoyed.

2. 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.

3. In the most unfortunate situation, we can compare the advantages and disadvantages and find something to comfort ourselves with.

4. As long as I can still paddle, I will not be drowned. As long as I can still stand, I will not fall.

5. Virtue despises all ridicule in the world. The more innocence is slandered, the higher the status.
