A teacher took several balloons to his school and gave one to each student. Then he asked each of them to write the name on his balloon and then leave it on the floor and leave the classroom. Once outside, I said to them: – You have 5 minutes to find the balloon that bears your name. The students came in and searched, but the 5 minutes ended quickly without anyone being able to find him. Then the master said: – Take any balloon and give it to the colleague who marked the name on that balloon. Within minutes, all students were already holding their own balloon in hand. Finally, the teacher said: – Guys, happiness is like balloons. Nobody finds it looking only for itself. Instead, if everyone cares about each other, you quickly find what you’re looking for.
