I think there are the following reasons for starting a family first and then starting a career:

If you are single, you will think that I am the only one. If you earn one hundred yuan today, you will use one hundred and ten yuan to make a living every day. How come to establish a career and start a family?

If you have a family and a house and earn 100 yuan today, you will think that I am older and younger, and you may have 90 yuan left. Only then will there be an opportunity to establish a career.

Besides, two people think more thoughtfully than one person. If two people think about how to start a business, they will have half the chance.

Furthermore, let’s use an analogy. You have always thought about establishing a career first and then starting a family. By the time you are 35 to 40 years old, you are still not considered a successful person, so you have to start a family by then. When you are in your fifties, you will have retired, but your children are still studying. That is when the most money is used, and then you have to go to work. I'm a lot older, and I still have to fight hard.

If you get married early, you will not become a successful person. But when you retire and your children go to work, won't you be able to enjoy happiness by then? It is better to fight when you are old than when you are young.

Maybe this is the reason why people have always said "start a family and start a business" for thousands of years instead of "start a career and start a family"!
