Success : The ulitmate goal

In media driven world, success is most regular used word at every section of news  from politics to bollywood everywhere. Generally we read lots of interview of successful person from different background and we are supposed to get inspiration from them. It seems success is only goal of life at any cost and we need to achieve it by whatever means. Then there is one question, what is purpose of any ones life?? To be successful or to have happiness in mind. We hear the word "casting couch" alot in news paper or magazine and we know what does it mean.
Is success is so much important in life that compel us to cross all boundaries and we work so hard to achieve it that we forget our all social and moral responsibility. I think in today's life getting money and fame defines success word. That means everyone running for this "success". What about our social and moral responsibility ??
Then how you do define success of farmers who are working so hard without much expectation from outside world and also struggles for getting right price of their crops. Is their success is small to famous and wealthy people. Although farmers are responsible for basic need of human being. If not then what is exact definition of success ?? Is success word's definition varies from person to person?? If yes then why we all compare all successful people in same way? Is it media's responsibility to project success of different people from different background in same way or its our to make distinction? Is media biased to some section of people ? Or we are becoming too materialistic ?
Very few know the Baba Amte who was an  social worker and social activist known particularly for his work for the rehabilitation and empowerment of poor people suffering from leprosy. He was restrict follower of Gandhism and practiced yarn spinning Chakra and wearing Khadi. In his last days he was fully involved in Narmada Bachao Andolan along with Medha Patkar which  fought against both unjust displacement of local inhabitants and damage to the environment on account of the construction of the Sardar Sarovar dam on the Narmada river. Is he not successful?
From my point of view these people are more successful than of our anyone else. Putting whole life  for the welfare of others without expecting in return is biggest sacrifice and not even for money or fame. Your contribution in solving problems of common man  defines success, bringing smile on sad face, giving food to hungry. After all Humanism is biggest religion.
