    A wise man used to go to the ocean to do his writing. He had a habit of walking on the beach every

morning.

    One day, when he was walking along the shore(海岸), he saw a young man moving like adancer. He

smiled to himself at the thought that someone would dance on the beach. So he began to walk faster to

catch up.

    As he got closer, he saw that the young man wasn’t dancing, but instead he was reaching down to the

shore, picking up something and very gently throwing it into the ocean.

    He called out, "Good morning! What are you doing?" The young man stopped, looked up and replied,  "Throwing starfish in the ocean." "I guess I should have asked, why are you throwing starfish in the ocean?"

"The sun is up and the tide(潮汐)is going out. And if I don’t throw them in, they’ll die."

     "But, young man, don’t you realize that there are miles and miles of beach and starfish all along it. You

can't possibly make a difference!"

    The young man listened politely. Then he bent down, picked another starfish, and threw it into the sea,

and said, "It made a difference for that one."

    There is something very special in each and every one of us. We have all been gifted(赋予) with the

ability to make a difference.

    We must each find our starfish. And if we throw starfish wisely and well, the world will be better.
