That's right, controlling money is the most difficult thing. Because trying to maintain wealth is very different from trying to gain wealth. Achieving wealth in a lot of ways, while maintaining wealth there is only 1 way, which is a combination of simple life and fear. In acquiring wealth we must take risks and remain optimistic.
whereas in maintaining wealth we must live more simply and have the fear that what we have accumulated over the years could disappear in an instant (not because it is stingy, but wise in spending money, can easily distinguish between wants and needs).
In essence I want to say one thing, maintaining wealth and seeking wealth are two different things, today many rich people can make much more money because they have the capital to try to get a source of income from several other things. As an example of building a business, investing and building something that can make money, then the risk will be proportional to the profit we get, the greater the risk, the greater the profit we will get.
A life lived in simplicity will be different and according to position, rich people will have a much more luxurious life and they will spend a lot of money for their living expenses, whereas those who seek wealth must definitely try to spend a little money. At some point the spending needs differ greatly between the rich and those who seek wealth.
I do not think that you understood what "income is not limited" part, it means that you could either find more work, or find another work. That way you would make more money, if you want to make more money then you need to work to find it at first and then you need to work to earn it as well. I have seen people who do all kinds of crazy work just to make some extra funds and I have done that myself as well before.
It matters if you end up with a solution that will fix things, and I bet that it is going to matter one way or another. I believe that we should not be doing anything that will challenge the situation all that much, do not go against the tide and just accept that you need money and get to working if you want that.
That's what I mean and the context can be seen from the way we get more jobs, when we work in many places with adjustable hours, our income will definitely be much greater. The problem is when someone tries to work in many places it will be difficult for that person to share their time, this is where intelligence is needed in allocating time or finding work that can be done by only being in one place.
In the last part I quite agree with you, that forcing something beyond the responsibility that we cannot afford will be far more at risk of losing everything. It's better to work according to what we are capable of being responsible for and not to force or even try to look capable, because living life is not only about work and there are other things that we also cannot ignore, health, free time and family
