In the movie Holy man, with Eddie Murphy,
the main character named G tells a story where he came into a beach with thousands of starfish laying on the beach dying.
He sees a girl throwing one starfish at a time back into the water. G asks her why she's trying so hard, because she can't possibly save them all.

She responds, to THIS one it makes a difference. And to THIS one it makes a difference!

In conclusion, thanks for paying it forward. To that one it made a difference!
