“Ender Wiggin isn't a killer. He just wins—thoroughly.”

“Be proud, Bonito, pretty boy. You can go home and tell your father, Yes, I beat up Ender Wiggin, who was barely ten years old, and I was thirteen. And I had only six of my friends to help me, and somehow we managed to defeat him, even though he was naked and wet and alone--Ender Wiggin is so dangerous and terrifying it was all we could do not to bring two hundred.”

“Come on,” he said to Valentine one day. “Let’s fly away and live forever.”“We can’t,” she said. “There are miracles even relativity can’t pull off, Ender.”“We have to go. I’m almost happy here.”“So, stay.”“I’ve lived too long with pain. I won’t know who I am without it.”So they boarded a starship and went from world to world. Wherever they stopped, he was always Andrew Wiggin, itinerant speaker for the dead, and she was always Valentine, historian errant, writing down the stories of the living while Ender spoke the stories of the dead. And always Ender carried with him a dry white cocoon, looking for the world where the hive-queen could awaken and thrive in peace. He looked a long time.”

“Every time, I've won because I could understand the way my enemy though. From what they did. I could tell what they though I was doing, how they wanted the battle to take shape. And I played off of that. I'm very good at that. Understanding how other people think. - Ender Wiggin”

“For the first time in his life, a teacher was pointing out things that Ender had not already seen for himself. For the first time, Ender had found a living mind he could admire.”

“Everything we do means something, Ender realized. Them laughing. Me not laughing. He toyed with the idea of trying to be like the other boys. But he couldn’t think of any jokes, and none of theirs seemed funny. Wherever their laughter came from, Ender couldn’t find such a place in himself.”

“He thought of half a dozen ideas before he went to sleep. Ender would be pleased-every one of them was stupid.”
