Well, the 'rightest' thing i've ever heard/read was written by Schopenhauer, where he said happiness is something unachievable, because it's human nature to eternally perceive something more. Money adds that up to its essence. I understand that hoping to get more money makes you feel some kind of joy, momentarily, but if it brough any happiness, why would, for example, Warren Buffet still make his life about money? He is over 80 and all he does is buy companies to make more money. He can buy anything.
In my opinion, there is a way of more satisfaction, and that's knowledge. It's not about showing off what you know, it's actually pretty selfish, just know by yourself, if makes you feel better. Things like understanding the universe, life and etc. Be that in a scientific or a philosophic way, it brings a sense of unimportance of you, and makes you stop having fear of irrelevant things, like lack of money, lack of love, family and etc.
But that's just me.
