Happiness is not found in pleasing others at the expense of self. It is not doing what others think you should do. Happiness comes when you do what pleases you for the sake of pleasing yourself. Think about this for a moment: No one could quibble that Mother Teresa was one of the most altruistic people of the 20th century. She didn’t have to do what she was doing. She did it because it pleased her. From my observation, she found profound personal pleasure in caring for others and serving God.
