Once a wise man held a seminar to teach people how to get rid of sorrows in their life. Many people gathered to hear the wise man’s words. The man entered the room and told a very funny joke to the crowd. The crowd 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 do you cry over the same problem over and over?”
