a hero is somebody who:
*does things even when they are scared
*does things even though they know they will not succeed
*does things you, or others, admire
*puts others before themselves
*achieves extraordinary things under unfortunate circumstances
*makes un-cool things really ridiculously cool
*is determined, courageous, brave, etc.
*admits they don't have the answers, but tries to find them anyway
*everyone pales in comparison to the hero
a hero is an example of how you would like to live for the rest of your life.
or who you would like to live the rest of your life for.
