There once lived a wise sage.
People were flocking to him complaining about the same problems to him every time.
One day , the wise sage cracked the joke and everyone roared in to laughter.
After couple of minutes, he then cracked the same joke second time and this time only few people were laughed.
When he cracked the same joke third time, no one was laughed anymore.
The wise sage then smiled and said - "You can't laugh at the same joke over and over, so why are you always crying on the same problems every time?"
The moral of the story is
worrying won't solve your problems, it will just waste your time & energy
