"Of all the work that is done or that can be done for our country, the greatest is that of educating the BODY, the MIND, and above all the CHARACTER, giving spiritual and moral training to those who in a few years are themselves to decide the destinies of the nation."- Theodore Roosevelt

I think that this statement means that if everyone has good body, mind, character then this country would be more united. In order to do this we must be more positive as well as be more friendly with each other.
