I've noticed that darn near everything is turned into a competition these days - not just sports or politics. You've said that the best way to make people do something is to "aim for their heart," and that fear and hope can be equally useful if the message is consistent. But which one is more powerful, hope or fear? Or does it depend on the situation? I can see where using fear to persuade could be dangerous, but is there ever a time where hope is dangerous?
