The following video is not only an excellent source of inspiration, it should be required viewing for all beings, human and otherwise.  For writers, I challenge you to create characters that not only arc in a way Aimee Mullins does but also have the layers of substance that propel them toward the climax of your story.  I also challenge you writers to put down your thesaurus and dictionary (on occasion) when you are looking for things that would ‘normally’ be the obstacle or conflict that your character must overcome.  Dig deeper than the standard definition, when you are creating a hero, there is no standard.

The video is 20 minutes and it will change the way you think, live and write.
