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 the 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.
