A wise man once encountered a group of people who were constantly complaining about the same issues. Instead of listening to their complaints, he told them a joke, and everyone burst out laughing.
The joke was then repeated by the man. Several people smiled.
Finally, the man told the joke a third time, but no one responded.
"You won't laugh at the same joke more than once," the man said with a smile. So what do you gain by continuing to complain about the same issue?"
You won't get too far if you only complain and do nothing about it. Don't waste time complaining; instead, take action to effect change.
