Quite a long time ago in a bazaar, five elephants performed carnival stunts. They were kept restricted with powerless rope that they might have effectively gotten away, however didn't.
At some point, a man visiting the carnival asked the ringmaster: "Why haven't these elephants split the rope and take off?"
The ringmaster answered: "From when they were youthful, the elephants were made to accept that they were not sufficiently able to break the ropes and getaway."
It was a result of this conviction that they didn't attempt to break the ropes now.
Lesson of the story
Try not to surrender to the constraints of society. Accept that you can accomplish all that you need to!
