“Long ago, there was a servant who served a bad tempered and impatient master. It did not matter how he tried, he was always blamed and beaten by this master. However, it was the strange truth that the servant was always happy, and his master was always sad and depressed. One day, there was a kind man who could not understand this phenomenon, and finally he decided to ask this servant why he was always happy even though he was treated so badly. The servant replied: “Everyone has one day of life each day; half of the day is spent awake and the other half is spent sleeping. Although in the daytime, I am a servant and my master treats me badly, in the nighttime, I always dream that I am a king and there are thousands of servants serving me luxuriously. Look at my master: In the daytime, he is mad, depressed, greedy, and unhappy. In the nighttime, he has nightmares and cannot even have one night of nice rest. I really feel sorry for my master. Comparing me to him, I am surely happier than he is.” Friends, what do you think about this story? You are the only one responsible for your happiness. If you are not satisfied and always complain about what you have obtained, you will be on the course of forever-unhappiness. It is said in the West: “If you smile, the whole world smiles with you, but if you cry, you cry alone.” What an accurate saying!”
