the fault in our stars by john green

"Much of my life had been devoted to trying not to cry in front of people who loved me, so I knew what Augustus was doing. You clench your teeth. You look up. You tell yourself that if they see you cry, it will hurt them, and you will be nothing but a Sadness in their lives, and you must not become a mere sadness, so you will not cry, and you say all of this to yourself while looking up at the ceiling, and then you swallow even though your throat does not want to close and you look at the person who loves you and smile."

"Some people don't understand the promises they're making when they make them," I said.

"Right, of course. But you keep the promise anyway. That's what love is. Love is keeping the promise anyway."

 "But I believe in true love, you know? I don't believe that everybody gets to keep their eyes or not get sick or whatever, but everybody should have true love, and it should last at least as long as your life does."

"Because there is no glory in illness. There is no meaning to it. There is no honor in dying of."

"The world is not a wish-granting factory."
