When she let the people into the other room, she asked them to find the balloon with their name written on it. And to do it within 5 minutes. Everyone set to work frantically looking for the balloon with their own name. They bumped into each other. Some even pushed others. There was much chaos in the room. At the end of 5 minutes, no one had found their own name.
Now, Sarah asked each person to collect a balloon at random and give it to the person whose name was written on it. Within minutes everyone had their own balloon.
This is exactly what happens in our lives. Everyone is frantically looking for happiness all around, not knowing where to find it. But if you give others their happiness, you will uncover your own happiness. This is the truth of happiness.
