They say, if you assess a fish by its ability to climb a tree, the fish will spend its entire life thinking that it is a failure.
Not true.
If you get a fish to climb a tree, the fish will realise that it is not cut out to climb trees. The fish becomes humbled by its inability to climb trees, and will seek to go back to the ocean. And learns to gather seaweed instead.
On the other hand, those who can climb trees will climb high enough till they can gather fruits for everyone on the ground.
The problem therefore, is not the system that tests your tree climbing ability. The problem is about fish not wanting to gather seaweed. The problem is about fish wanting to take the place of those who can climb trees. That is the problem.
