Income is not in direct proportion to expenditure. What are they?

The statement that income and expenditure are not proportional:

1. Sometimes I feel like a fool and an idiot. I think how good I am to others will get the same reward. I'm such a fool. How can I be so good? Pay is not proportional to return.

2. Pay and return are in direct proportion, but many times pay and return are not in direct proportion.

3. Sometimes it's really not proportional to pay and return, and it's cold to think about it. But that's life. How versatile you are if you can satisfy everyone. So it is good to have a clear conscience.

4. Pay is not directly proportional to return, and who can persist? People who have passed ahead of time are still thinking about it, and they don't know how to persist. Persistence has no result.

5. When the pay is not proportional to the return, it will start to haggle over every ounce. I'm really not fit to live in groups. This is a hard day to die and a day to be looked down upon.
