Happiness is what every human should strive for

Happiness is the emotion in which one experiences feeling ranging from contentment and satisfaction to bliss and intense joy. I think happiness is the one thing that every human should strive for/ seek for or pray for. It looks like everything else is included in happiness. If we pray for happiness, for example it will include our health, wealth, sustenance (roti/food, kapda/clothing, makan/housing). Not only that. Even if we (our own household/family) are well off, we might not be happy if a brother or sister or parent or in-law or cousin are having some problems. We will have some dissatisfaction because of that. So to be completely happy all the above mentioned persons should be happy. Apart from that, if a neighbor is unhappy for some reason, it will in one way or other affect us and will not let us be completely happy. Basically every one has a certain set of individuals that need to be happy for them to be happy. For example if I need to be happy, my sister needs to be happy and for her to be happy, her husband and children need to be happy. If you extend that argument, for us as an individual to be truly happy we will need every other human being to be happy.
