Lay down 2 bottles, leave the cap opened, and light up the bottom of the bottle. Put some bees in one bottle, and put some flies into the other one.
All the bees fly to the light direction until they hit the bottom of the bottle, they will keep hitting until they die. The flies will fly to the light direction too, when they hit the bottom, they will try another direction, until they fly out from the bottle.
We are the bees, stubborn most of the time, we wont change even though we knew it’s wrong. We should act like the fly, try different approach, and manage to fly out from the bottle one day.
