A person's life is limited; if you're going to make money, make big money.

There's a popular saying:
A horse doesn't get fat without night grazing; a person doesn't get rich without sudden wealth.
Graduated in your twenties with no money to start a business, working casually for a few years, soon approaching 30, getting married soon after, then having a child.
At this time, in your thirties, with elders above and children below, you dare not start a business.
Spending a few more casual years, you're almost 40, your child has grown up, and you're about to be laid off.
So, life is limited; time flies like the swift sun and moon.
You must seize the time to get rich quickly.
That's why every time, you need to heavily invest and work hard, with gains and losses, increasing your position, not wasting time and opportunities.
Otherwise, you might as well go to hell.
