Can I make a difference?

Im sure youve read this poem Im sharing today.
I was lying in bed sobbing.
P and I were discussing a child we had to leave behind.
I have to know we are making a difference
even if its just one.

A man was walking along a beach upon which thousands of starfish had been washed up. Left on the sand by the receding tide the starfish were certain to die as the sun dried them out. The man also saw a boy picking up starfish and flinging them back into the sea. Planning to teach the boy a little lesson in common sense, the man walked up to the boy and said, "I have been watching what you are doing, son. You have a good heart, and I know you mean well, but do you realize how many beaches there are around here and how many starfish are dying on every beach every day? Surely such an industrious and kind hearted boy such as yourself could find something better to do with your time.
Do you really think that what you are doing is going to make a difference?"
The boy looked up at the man, and then he looked down at a starfish by his feet.
He picked up the starfish,
and as he gently tossed it back into the ocean,
he said, "It makes a difference to that one."
