Wise old cat observing a kitten chasing its tail:

“Why are you chasing your tail so?" asks the old wise cat.

The kitten replies, “I have learned that the best thing for a cat is happiness, and happiness is in my tail. Therefore, I am chasing it, and when I catch it, I shall have happiness."

The wise old cat responds, “I too have judged that happiness is in my tail. But I notice that whenever I chase it, it keeps running away from me. And when I go about my business of being a proper cat, it just seems to come after me wherever I go."
