Here are some quotes that I liked from The fault in our stars by John Green:
"I fear oblivion."
"Why are you looking at me like that?
(...) Because you're beautiful. I enjoy looking at beautiful people, and I decided a while ago not to deny myself the simpler pleasure of existence."
"You put the killing thing right between your teeth, but you don't give it the power to do its killing."
"Sometimes, you read a book and it fills you with this weird evangelical zeal, and you become convinced that the shattered world will never be put back together unless and until all living humans read the book."
“That's the thing about pain...it demands to be felt.”
“You don't get to choose if you get hurt in this world...but you do have some say in who hurts you. I like my choices.”
“What a slut time is. She screws everybody.”
“There are infinite numbers between 0 and 1. There's .1 and .12
and .112 and an infinite collection of others. Of course, there is a
bigger infinite set of numbers between 0 and 2, or between 0 and a
million. Some infinities are bigger than other infinities. A writer we
used to like taught us that. There are days, many of them, when I resent
the size of my unbounded set. I want more numbers than I'm likely to
get, and God, I want more numbers for Augustus Waters than he got. But,
Gus, my love, I cannot tell you how thankful I am for our little
infinity. I wouldn't trade it for the world. You gave me a forever
within the numbered days, and I'm grateful.”
“The marks humans leave are too often scars.”
“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.”
“Grief does not change you, Hazel. It reveals you.”
