Nature's first green is gold,
Her hardest hue to hold.
Her early leaf's a flower; 
But only so an hour.
Then leaf subsides to leaf,
So Eden sank to grief,
So dawn goes down to day
Nothing gold can stay.

In a spell of dry weather, when the Birds could find very little to drink, a thirsty Crow found a pitcher with a little water in it. But the pitcher was high and had a narrow neck, and no matter how he tried, the Crow could not reach the water. The poor thing felt as if he would die of thirst. Then an idea came to him. Picking up some small pebbles, he dropped them into the pitcher one by one. With each pebble the water rose a little higher until at last it was near enough so he could drink.

One summer's day, a merry Grasshopper was dancing, singing and playing his violin with all his heart. He saw an Ant passing by working hard to store food for the winter. “Come and sing with me instead of working so hard,” said the Grasshopper “Let’s have fun together.” “I must store food for the winter,” said the Ant,“ and I advise you to do the same.” “Don’t worry about winter, it’s still very far away,” said the Grasshopper, laughing at him. But the Ant wouldn’t listen and continued to work. When winter came, the starving Grasshopper went to the Ant’s house and humbly begged for something to eat. “If you had listened to my advice in the summer you would not now be in need,” said the Ant. “I’m afraid you will have to go without supper,” and he closed the door.

A Dog, to whom the butcher had thrown a bone, was hurrying home with his prize as fast as he could go. As he crossed a narrow bridge, he looked down and saw his reflection in the quiet water as if in a mirror. But the greedy Dog thought he saw a real Dog carrying a bone much bigger than his own. If he had stopped to think he would have known better. But instead of thinking, he dropped his bone and sprang at the Dog in the river, only to find himself swimming for dear life to reach the shore. At last he managed to scramble out, and as he stood sadly thinking about the good bone he had lost, he realized what a foolish Dog he had been.

All Cameron wanted to do with his life was be a singer. He didn't pay attention in school and he spent all of this time at home watching music videos online and impersonating his idols. His mother tried to teach him the value of getting an education and having a backup plan, but Cameron would respond the same way every time, "Mom, I won't need to know any of that boring old stuff when I'm famous, You'll see." But there was one major problem with Cameron's plan; wasn't any good at singing. Cameron wanted to be a singer so badly, that he didn't notice the pained look on the faces of those who endured his singing. Because he wanted to be a singer to badly, when honest people told him to find something else to do with his life, he accused them of being "jealous haters" and ignored their advice. After Cameron dropped out of high school to focus on his music career, the years passed and the doors never opened.
