why is everyone want to happy?

is every one happy?

Now a days, Every wants to happy and its their right to be.. and while secondary level differences on nationality, family,faith, social status and so on.. more important that on human level we are all the same... No one wants to face the real problem and yet we create them by stressing our differences. If we see each other as such a fellow human being, there will be no basic for fighting or conflict between us..
