Myth Called Happiness

The title is not an attempt at making any claims for I am not that enlightened .Its just a silent contemplation in words.Is happiness for real ? Can it ever be achieved? I always feel there's something missing inside me keeping me from attaining this state of feeling happy and contended and once I achieve this thing , my life will be as radiant as a meteor sitting cozily in the gaudy company of 'perfect category lives'. The lives that appear to be perfect , some friend's or some friend's sister or some friend's friend's.... How would it feel to know , acknowledge and feel happy.Are there any people who can call themselves happy? Because there is always something... something that's missing,Once we achieve that thing.. something else comes along. Is it naive dreaming to achieve that state when you know you have a 'perfect life'? Is it like chasing the end of the rainbow? Perhaps its all about moments.We have some joyful moments until something comes along that casts these clouds of despair and we realize we are unhappy , but we still have those moments.We think about them , almost feel them , sometimes they torment us, sometimes they comfort us.Is this thing called happiness just a myth?
P.S. I have watched this movie called pursuit of happiness.But then it was a movie!
