Inspiration

The other day I saw a movie called Dirt, and in it a woman told a story that went something like this:

One day there was a huge fire in the forest.  All the animals ran from the forest to the edge of the lake, where they helplessly watched the fire consume their homes.  After a little while, a hummingbird takes off, picks up a drop of water from the lake in his beak, flies over to the fire and drops the water on it.  He does this over and over, and the other animals ask him - "What are you doing?  You are too small to make a difference".  And the hummingbird answered - "I'm doing what I can".
