Once upon a time there was a rich man. He had a lot of money, but he felt unhappy all the times. Finally, the rich man left for home to look for happiness. He visited many places and met many rich men. All of them said they were not happy, too. On his way home, the rich man saw a farmer work in the field. He went up to the farmer and asked, “Could you tell me if you felt happy?” “Yes, I’m quite happier. I always feel satisfying about everything in my life,” the farmer answered. “Please tell me how you find happiness,” asked the rich man. The farmer answered with smile on his face. “It’s very easy of me to answer the question. If you work hardly, have three meals a day and go to bed early without worries, you’ll be the happiest man in the world.”
