I am reminded of the story of a little boy walking along the beach with his Dad. There are hundreds of starfish that have been washed up on the shore, but are still alive. The boy starts picking up starfish and tossing them back in the water.
"Son, you are wasting your time. This beach goes on for miles. You could not make a difference".
The boy picks up a starfish and tosses it into the water. "I made a difference for that one."
