Let start with definition of happy. I think we have to seeking it between of relations. happiness depend on that people how behavior with you. if they respect to you, if they say compliments to you, if they satisfy you, you will feel happiness. when you are looking people care to you and you are important for them, it make feeling good in you. Separate of your position in family or your job or your neighborhood, happiness will back to your relationships. So be happing relate to be kindness with others. Share kindness in the world to make happy your self.
