The Clever Crow
A crow, who had nothing to drink for a long long time, came across a water bottle which had once been full of water. When the crow put his beak into the opening of the bottle, he found he could not reach the small amount of water that was left at the bottom. He tried and he tried and was about to give up when he saw some small rocks. He picked up the rock and dropped it into the bottle. He picked up another and dropped it in as well. He kept dropping the little rocks into the bottle until finally the water had risen enough that he could get a drink.
Little by little you will finally get things done.
