Leadership

In the northwest corner of the world, there was a village in a forest.
The village was led by three powerful men, who proved to be fierce warriors and hunters.
One day one of the younger men of the village was tasked with preparing and cooking the freshly caught fish for the village.
One of the village leaders came by to tell the younger man to skewer the fish and roast them over the fire.
The young man began slowly cooking the fish over the fire rotating them every so often.
A few minutes later the second village leader stopped by to check on how cooking the fish was going.
He asked the young man why he was roasting the fish as opposed to baking them in aluminum foil.
The young man told the second village leader that he had been told to cook the fish that way by the first village leader.
The second village leader insisted that his method would be a more efficient way cooking the fish.
So then the young man switched methods of cooking the fish for several minutes.
The third village leader came along to check on the young man.
He asked the young man why he was cooking the fish in aluminum foil when they had frying pans.
Again the young man explained to the third village leader that he had been instructed by the second leader to cook the fish in the foil.
The third leader told the young man to cook the fish in the frying pans.
After the third leader left the young man was left very confused.
While he understands that there are multiple ways he can complete this task he is unsure of who to listen to.
So he decides to cook the fish as the third leader had instructed him too and brought the cooked fished to the village.

What does this teach us about leadership?
