A man watched as a butterfly struggled to emerge from its cocoon, and decided to help by cutting open the cocoon. However, the butterfly's body was small and shriveled, and its wings did not expand properly, so it was never able to fly. The struggle within the cocoon is necessary for the butterfly to pump fluids into its wings to prepare for flight. Similarly, struggles in life strengthen us and without obstacles, we would not grow strong enough to achieve our potential.
