“I don't care if I pass your test, I don't care if I follow your rules. If you can cheat, so can I. I won't let you beat me unfairly - I'll beat you unfairly first.- Ender ”
“People don't care how much you know unless you know how much you care”
“I don't care how wonderful heaven is, I won't be content waiting thirty years for you.”
“People don't care how much you know until they know how much you care”
“I can't tell you how much I don't care.”
