We can't literally have all the money in the world but we need this money and there's no amount which can be enough because the more money you make the more your wants, tastes and desires changes and to meet up means more quest for more money.
in that case you should definitely change your mindset because this is just greedy yes we can't have all money in the world that is because it is infinite and the more money you get the more money is distributed i believe that at some point you can be comfortable and not worry about your money you just have to learn how to be content as long as you can sustain yourself and family and also be prepared for emergencies then i think that is a good enough life where i can be comfortable and secure
