from nobody to heros

When I think of nobodies that became heros I think of the WU nursing studants that riskeed their lives to save a man that they didn't even know. And by trying to do so they changed there lives also. They were doing what they were taught to do, and that is to help and care, and it turned out much differently than expected.

Another example of a nobody that became a hero is Snow White in the movie "Mirror Mirror", the movie puts a twist on the original fariytale. The wicked Queen keep Snow White on the castle while she destroys and takes from the village. Once Snow is taken to the woods to be killed, but is let go she becomes the hero. She takes back her kingdom!
