By having an income that can only cover a month's needs, of course we have to look for additional income to be able to save because if we have an income that is only enough for a month's needs and don't have savings for emergency needs, it will certainly be very difficult for us if we get unexpected needs, of course we have to take on debt to meet these needs.
If we choose to invest, of course we have to do it consistently and also use strategies in the investments we make to gain profits. Yes, you are right, we have to keep control of our expenses so we don't use them for things that are not important.
Logically, we can only save when all our living needs have been met, so there are several steps we must take first to be able to achieve our desired goal, namely being able to save.
Regarding earning extra money because the main income is only able to meet life's needs, we will have additional tasks and we have to do that because it is impossible to live by just watching without making any progress.
Do extra work to have more income, then apply strategies in life to be able to save or invest, those are different plans in my opinion, the most important thing is that we have to have more money first to be able to do all these things.
