"Few are willing to brave the disapproval of their fellows, the censure of the colleagues, the wrath of their society. Moral courage is a rarer commodity than bravery in battle or great intelligence. Yet it is the one essential, vital quality for those who seek to change a world that yields most painfully to change. Each time a person stands up for an idea, or acts to improve the lot of others, or strikes out against injustice, (s)he sends forth a tiny ripple of hope, and crossing each other from a million different centers of energy and daring, those ripples build a current that can sweep down the mightiest walls of oppression and resistance." --- Robert F. Kennedy
