In pursuit of happiness

I wonder if there would be a single sane human being in this planet who would not want happiness. Unless until he is suffering for a cause. We all are in pursuit of happiness. It is after all a state of mind. Confucius says, " once you are aware that you are happy, your happiness ends". If so, is it a state of forgetting our Self - our bundle of anxieities, aspiration, hatred, jealousy, secret agendas etc. If only briefly.
There are certain basic needs which have to be met in order be comfortable. I am happy to find water when i am thirsty; food when I am hungry, a toilet when I have the nature's call. But then these are momentary 'pleasures'. What would give me perpetual happiness - absolute, unconditional bliss ? Rishis have, since aeons, had their supreme goal as the 'anandha' - bliss. we ordinary mortals, treading this 21st century would want a 'understanding' (read acceding to all wishes) family, peaceful workplace, and a enlightened society. But I am also a part this society - as an individual member. what is my contribution to make others happy. If only I am happy and and don't care about others. Is it not selfishness ?
We are born crying, but want to live laughing ! But we were also born happy - after a long stay in a dark and cramped up space called uterus. All our needs taken care of by that angel called mother. she feeds us when hungry, cleans our excreta, sings us songs ( or atleast plays the music system). we were very happy then. How then we lose our happiness.
When we developed desires, ambitions. But ambitions are good. everyone should have them. To motivate ourselves to achieve. In order to.....? In order to be happy. oh..what have we done. We have set ourselves conditions to be happy. we will not allow ourself to be happy if we do not attain certain materialistic gains. Our happiness is conditional.
