not at all. Happiness does not depend on money. It is more like a psychological thing which is more connected to the human minds. Don't you think so?
Yes, money only buy temporary happiness in terms of material things that makes an individual fulfill his/her wants and needs. Love, family, partner, success, health, etc. is much more important to attain true happiness in life. So, not all depends on how much money that we have but how we create good relationships to our family, friends, and other people surrounding us.
