Ten unforgettable quotes from "The Fault in our Stars" echo the story of two cancer-stricken teenagers who fell in love with each other. Recall Hazel and Augustus' concern for each other through these thoughtful lines from John Green's novel.

We listed ten for you:

1. "Without Pain, How Could We Know Joy?"

2. "The real heroes anyway aren't the people doing things; the real heroes
are the people NOTICING things, paying attention. The guy who invented the smallpox vaccine didn't actually invent anything. He just noticed that people with cowpox didn't get smallpox."

3. "I hated hurting him. Most of the time, I could forget about it, but the inexorable truth is this: They might be glad to have me around, but I was the alpha and the omega of my parents' suffering."

4. "I'll give you my strength if I can have your remission."

5. "I knew that time would now pass for me differently than it would for him-that I, like everyone in that room, would go on accumulating loves and losses while he would not. And for me, that was the final and truly unbearable tragedy: Like all the innumerable dead, he'd once and for all been demoted from haunted to haunter."

6. "Do the thing you're good at. Not many people are lucky enough to be so good at something."

7. "Good friends are hard to find and impossible to forget."

8. "You are going to live a good and long life filled with great and terrible moments that you cannot even imagine yet!"

9. "I always had this secret suspicion that I was special."

10. "Even then, it hurt. The pain was always there, pulling me inside of myself, demanding to be felt. It always felt like I was waking up from the pain when something in the world outside of me suddenly required my comment or attention."
