The purpose of our life needs to be positive. We weren't born with the purpose of causing trouble, harming others. For our life to be of value, I think we must develop basic good human qualities - warmth, kindness, compassion. Then our life becomes meaningful and more peaceful - happier.
Human beings by nature want happiness and do not want suffering. With that
feeling everyone tries to achieve happiness and tries to get rid of suffering, and everyone has the basic right to do this. In this way, all here are the same, whether rich or poor, educated or uneducated, Easterner or Westerner, believer or non-believer, and within believers whether Buddhist, Christian, Jewish, Muslim, and so on. Basically, from the viewpoint of real human value we are all the same.
