Starfish Story, often cited in seemingly dauntless tasks of social change:
“While wandering a deserted beach at dawn, stagnant in my work, I saw a man in the distance bending and throwing as he walked the endless stretch toward me. As he came near, I could see that he was throwing starfish, abandoned on the sand by the tide, back into the sea. When he was close enough I asked him why he was working so hard at this strange task. He said that the sun would dry the starfish and they would die. I said to him that I thought he was foolish. there were thousands of starfish on miles and miles of beach. One man alone could never make a difference. He smiled as he picked up the next starfish. Hurling it far into the sea he said, "It makes a difference for this one." ” ― Loren EiseleyMy ornament has "It makes a difference for this one, 2013" written on the bottom.
