Once upon a time, in a big wild forest, there lived a little black cat. The black cat was very sad because it could not climb trees like the other cats. Every day, the black cat would look up at the tall trees and wish it could climb them too.
One sunny day, the black cat decided to try to climb a tree. It tried very hard, but it could not go up. The black cat felt sad and sat down under the tree. A kind bird saw the black cat and flew down to help. The bird told the black cat, "Don't give up. Keep trying, and one day you will climb the tree."
The black cat listened to the bird and tried again. This time, the black cat went up a little bit. The black cat felt happy and kept trying. Every day, the black cat tried and tried, and it went up higher and higher. Finally, the black cat could climb the tree just like the other cats. The black cat learned that if you try and don't give up, you can do anything you want.
