When there is too much stress or worry, look within.
Everyone wants to be happy; happiness is a right. And while on a secondary level differences exist of nationality, faith, family background, social status and so on, more important is that on a human level we are the same. None of us wants to face problems, and yet we create them by stressing our differences. If we see each other just as fellow human beings, there'll be no basis for fighting or conflict between us.
