“Are you reading your Bible?"Ah, well...I was."And then you quit."You got it."Then, you can expect to be weak on one of your flanks, and that's precisely where the Enemy will come after you with a vengeance.”

“An enemy, Ender Wiggin," whispered the old man. "I am your enemy, the first one you've ever had who was smarter than you. There is no teacher but the enemy. No one but the enemy will tell you what the enemy is going to do. No one but the enemy will ever teach you how to destroy and conquer. Only the enemy shows you where you are weak. Only the enemy tells you where he is strong. And the rules of the game are what you can do to him and what you can stop him from doing to you. I am your enemy from now on. From now on I am your teacher.”

“I am your enemy, the first one you've ever had who was smarter than you. There is no teacher but the enemy. No one but the enemy will tell you what the enemy is going to do. No one but the enemy will ever teach you how to destroy and conquer. Only the enemy shows you where you are weak. Only the enemy tells you where he is strong. And the only rules of the game are what you can do to him and what you can stop him from doing to you. I am your enemy from now on. From now on I am your teacher. I will devise the strategy of your army, and you will learn to be quick and discover what tricks the enemy has for you. Remember, boy. From now on the enemy is more clever than you. From now on the enemy is stronger than you. From now on you are always about to lose.”

“Would you give up your vengeance against someone you hate if it meant saving someone you love? Would you want your dreams to come true if it meant granting your enemy's dying wish?”

“It's dangerous to let your enemy see weakness. Weakness can git you killed.”

“How do I know I can trust you?''You can't,' he said bluntly. 'You've got to take it on faith that the enemy of your enemy is your friend.”
