Finding the value of happiness.

And another week passed feel much more better now,although I finished reading"blind owl".It made me upset at first,then I wondered why a person,genius and educated like Hedayat shall must think so?Why was he so sad and upset with life?I can't get him,and I dare to say that I can never ever agree with him belive life goes on with it's own happiness and sadness,but it's wrong to just see and think about dark and bad points of it is the most valuable gift ever given to human,and it's the most great,passionate,and joyful song ever composen.Each human is a note,a lonely not is no song,so we most be together and try to make a good one belive our duty is to contribute a versa to the universe and people.
