In India, they have elephants in the same way we have cattle (they consider cows holy, and therefore don't keep them in captivity). When a baby elephant is brought to the farm, it is tied to a pole with a very thick rope, and then left to tug and pull for its escape. When it grows older, it of course becomes stronger, and becomes increasingly capable of snapping the rope it's ******* with. The farmers, however, use an increasingly thin rope - the elephant gets so used to the limitation, that it learns to go in the direction of the tug, instead of against it. In the end, the farmers walk around with incredibly strong, heavy, dangerous elephants in nothing but strings of grass. The elephants are broken in, and no longer see the opportunities right in front of them. In the same way, human potential is almost limitless, yet we get used to limiting thoughts and mindsets - we have, deep down, the ability to do insane stuff.
