If you ask me, I would suggest try to do some social activities. For instance, help to the orphans, or old people or the handicap or under previledge people and so on. Trying to fit oneself in this domain may particularly, make you happy. And at the end of day, realize that how much progress have you made so far. On contrary, I myself haven't entered in this domain yet. Hope One day, if such feelings comes to my mind.
