The fuel from an enemy.

Amazing the fuel an enemy can give. They can motivate you so much. Their attempts at a sabotage of your life, only improves it. When you are kicked for so long, you sometimes become numb to the kicking. So, the repeated abuse you endure hurts you no more. There is nothing to bring you more pain. Heartache or discomfort. As much as your enemy tries they cannot bring you down further. Because you are already there. But, when you stand up. You have such a resilience to any form of pain, attack, or just evil strike. That, nothing can knock you down again. Or for that matter, hold you down. All thanks to the fuel an enemy can give.
