I was walking down the street in New York City one day, when I heard a woman's voice saying, "I was very sick all winter." Intrigued, I turned around and saw the woman handing a street person, sitting on the sidewalk, some money. She went on talking to him. "I had pneumonia, and every time I started to get better, I'd have a relapse. Now I am finally really getting better, and I just wanted to share the joy."
Gratefulness has three steps: not missing the opportunity, appreciating the opportunity, and using or enjoying the opportunity. By this method we come fully alive, full of joy, which is what we are all longing for.
