Many times ago, a man was walking along a beach at which he saw a boy who stod by the shore and was trowing things into the water.
As he aprotched he saw him throwing sea stars into the water, upon this the man asked the boy why he did so where the child awnsered: "As the tide is going back I help the little creatures as to get back into the water so they do not die."
The man looked back and forth and started to luagh softly; "Do you not realize the futility boy? The beach is miles long and there is thousends of them at the least, you cannot make a difference."
The boy gave a polite bow after listening, picked up another sea star and throw it back into the water, which upon he said smiling to the man: "I made a difference to that one."
It's not about solving everything, but taking your part in the sulotion.
