What would be the source of the true happiness that we're longing to have? The world? Job? Family ? Money? Good background? Are they worth enough bases to be truly happy ?
More of us are unhappy of their life, unhappy of their married life etc. But it depends to people how they handle their feelings and how they manage their lufe to be happy. Sometimes we choose to be happy..
I think it is important to remember that some of the most unhappy and unfulfilled people are those who are very wealthy and successful, the rich and powerful are almost never satisfied and filled with a constant drive to assert their egos ambition. Of course this drive is what made them successful, but they forgot that wealth and power over others is not the highest goal. To find the riches within oneself and the power over the control of the lesser self is the goal of life.
