People have been coming to the wise man, complaining about the same problems every time. One day he told them a joke, and everyone roared in laughter.
After a couple of minutes, he told them the same joke and only a few of them smiled. When he told the same joke for a third time no one laughed 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.
