One day a man decided to change the world. But he realized before he can change the world, he must first change himself. This was the details of his realization;

He realized, if he change himself, it will have effect on those living with him in house and they will also change. If those in the house change, it will have effect on those in the community and they will also change. If those in the community change, it will also have effect on those in the town and they will also change. If those in that town change, it will have effect on those in the region and they will also change. If those in the region change, it will have effect on those in the country and they will also change. If those in the country change, it will have effect on other countries and the whole world will then also get changed. In the same way if we try and change our way of life and live a good life,those around us , and the world as a whole can also get changed.
