A professor gave a balloon to every student, who had to inflate it, write their name on it and throw it in the hallway. The professor then mixed all the balloons. The students were then given 5 minutes to find thier own ballon. Despite a hectic search, no one found their balloon.
At that point, the professor told the students to take the first ballon that they found and hand it to the person whose name was written on it. Within 5 minutes, everyone had their own ballon.

The professor said to the students: " These balloons are like happiness. We will never find it if everyone is looking for thier own. But if we care about other people's happiness, we'll find ours too."
