The problem is that the modern world has tied it's happiness around money and physical assets, while these can bring satisfaction, they shouldn't be a hallmark of happiness. This is because once they are gone, happiness automatically disappears. True happiness should be from your everyday life and the relationship you have with people irrespective of social status and financial status.. this helps you see the good in people and the positives side of living away from the aspect of money.
In the contemporary society many people is full of greed. Driven by money and physical asset. And when their desire and quest for monetary value are not met they are depressed some even commit suicide. It is better to avoid such people because that state of mind is like an infectious disease. Unhappy people can do anything out of greed. Unhappy people thinks their happiness is tied to money and physical asset. Rather they forget that if they are not happiness personified money and physical asset will only be a vehicular tools for greedy living.
