What I want!?

Life has become like race with sometime a shorter while most of the bigger target which always stay ahead to make me run! and in between all these challenges of life there always remains the question that, what I want?...some time look like myself running in a blind race in which I am heading nowhere...even after all my efforts even when I achieve something questions remains in mind that, "probably this is not something which I had demanded from life!!!"...totally confused as always! but can't stop even to sit and think of...
