Once upon a time, there was a fat cat. The cat liked to play with a tool. The tool was a ball. The cat played with the ball all day.
One day, the cat wanted to improve. The cat wanted to jump high and run fast. The cat thought, "If I am not fat, I can jump and run better." So, the cat played with the ball more and more.
Then, something unexpected happened. The ball got bigger and bigger. The cat was surprised. The cat played with the big ball, and the cat got thin. The cat could jump high and run fast. The cat was happy. The moral of the story is: play and have fun to improve and be happy.
