We've all seen stories featuring main characters that take pain for the sake of protecting others, even when they end up bloody and bruised because of it. While this kind of wish fufillment is cool and all, most people wouldn't go that far (and shouldn't be expected to). There are plenty of stories that feature more normal feats such as befrending those who're bullied, or helping those in need. In any case, are there any tv shows/movies/books/etc that influenced you to be more heroic, and how did you change as a result?
