At what point will one say that he or she has had enough money?
Contentment is great gain.
The fact is that there's never a point where the thirst for money is ever satisfied, it's like a bottomless pit.
However, what would help you is Contentment. Do not live above your means. Do not see it as diminishing to accept that you can't afford it when you truly can't.
Above all, do not wish to be like someone else, you'll be amazed at how many people wishing to be like you.
Just be you and be kind.
Ciao.
