* Heroes are often ordinary people who rise to the occasion. This is a common theme in American literature, from the early days of the Republic to the present day. Heroes like David Crockett, Abraham Lincoln, and Martin Luther King, Jr. are all examples of ordinary people who did extraordinary things.
* Heroes are often defined by their actions, not their words. Americans tend to be action-oriented, and our heroes reflect that. We admire people who do good things, not just people who talk about doing good things.
* Heroes are often flawed. No one is perfect, and our heroes are no exception. They often have flaws that make them relatable and human. This can make them even more inspiring, as they show us that it is possible to overcome our own flaws and achieve great things.
* Heroes are often symbols of hope. In times of crisis or despair, we look to our heroes for hope. They remind us that there is always good in the world, even when things are tough.
Of course, there are many exceptions to these general rules. Not every hero is ordinary, not every hero is defined by their actions, and not every hero is flawed. But the above observations provide a general overview of how heroes are created in the United States.
