it is difficult to analyse why people are unhappy even though they have anything in their life.various resons are there, It depends on the individual. I believe most all people want always to be happy in their life, whatever their conditions. In other hands, happiness is the goal of human being. However, in some conditions they may feel unhappy for some reasons or even there is no caused for being unhappy. For me, being happy is not complicated, just be calm and enjoy the life. Always thankful for what God gives to us. Do not see other, concerning to what we have. Even the richest people on earth are not happy simply because people are not contented with what they have. Happiness cannot be found in the luxury cars and cozy home, neither in the millions of dollars and jewelries, nor fame and power if you are surrounded with fake people. One can have true happiness by being contented with simple things, like a not so expensive houses and less material things. Having a pure heart without hatred, unselfish acts and a clean concience are enough to make someone happy inside and will eventually show in the outside. Those are things that money cant buy.
