For me True "Wealth" is just simpy the ability to do or buy something without worrying about the cost of that something.
If I want to have a vacation abroad, then I'll just simply book the earliest flight possible without even looking at how much the cost is. If I want a new car because I am now bored with the color of the previous one, I just go buy another one irregardless of the cost.
Hate it or not, Wealth is directly linked to money and is by extension linked to one's wants and needs. The feeling of not having to worry about financial aspects makes one live a very carefree and stress-free life.
