People visit a wise man complaining about the same problems over and over again. One day, he decided to tell them a joke and they all roared with laughter.
After a few minutes, he told them the same joke and only a few of them smiled.
Then he told the same joke for a third time, but no one laughed or smiled anymore.
The wise man smiled and said: “You can’t laugh at the same joke over and over. So why are you always crying about the same problem?”
Moral of the story: Worrying won’t solve your problems, it’ll just waste your time and energy.
