I think that everyone can start from himself that dont look to be rewarded being good person doing good things to people but look at it from ur own view that I wanna be a good person no matter at all people do or beleive in , and may be by doing good other people would be look at u as a model beleive me there still people u can affect them it also may variet between people
u can start from ur self..thats a good start and u will raise ur family at the same good morals by being the modal...and people around will always be affected
