“I think people think that being a teenager is all about fun, but what it is about is responsibility.”

“You’re not responsible for what people think about you. But you’re responsible for what you give them to think about you.”

“There's no doubt about it: fun people are fun. But I finally learned that there is something more important, in the people you know, than whether they are fun. Thinking about those friends who had given me so much pleasure but who had also caused me so much pain, thinking about that bright, cruel world to which they'd introduced me, I saw that there's a better way to value people. Not as fun or not fun, or stylish or not stylish, but as warm or cold, generous or selfish. People who think about others and people who don't. People who know how to listen, and people who only know how to talk.”

“They've been talking about their prom nonstop. Even the people that think it's a “joke” like Mary Elizabeth can't stop talking about what a “joke” it is. It's all very fun to witness.”

“I was thinking about all these things and more, but I wasn't really thinking about them at all. They were just there, floating around in the back of my mind, thinking about themselves. What I was really thinking about, of course, was Lucas.”

“Worry less about what other people think about you, and more about what you think about them.”
