“Human progress isn't measured by industry, it's measured by the value you place on a life. An unimportant life. A life without privilege. The boy who died on the river, that boy's value is your value. That's what defines an age. That's what defines a species.”

“Some people live more in 20 years than others do in 80. It’s not the time that matters, it’s the person.”

“The way I see it, every life is a pile of good things and bad things. The good things don’t always soften the bad things, but vice versa, the bad things don’t always spoil the good things or make them unimportant.”

“Nothing’s sad until it’s over, and then everything is.”

“Everything’s got to end sometime. Otherwise, nothing would ever get started.”

“We’re all stories, in the end. Just make it a good one, eh?”

“Never be cruel. Never be cowardly. Hate is always foolish. Love is always wise. Always try to be nice, but never fail to be kind.”

“Who I am is where I stand. Where I stand is where I fall.”

“Do you know what thinking is? It’s just a fancy word for changing your mind.”

“I’m old enough to know that a longer life isn’t always a better one. In the end, you just get tired; tired of the struggle, tired of losing everyone that matters to you, tired of watching everything you love turn to dust. If you live long enough, Lazarus, the only certainty left is that you’ll end up alone.”

“I can't! Why is it always me? Why is it never anybody else's turn? Can't I just lose? Just this once?”

BILL: So, the Time Lords, bit flexible on the whole man-woman thing, then, yeah?

DOCTOR: We're the most civilised civilisation in the universe. We're billions of years beyond your petty human obsession with gender and its associated stereotypes.

BILL: But you still call yourselves Time Lords?

DOCTOR: Yeah. Shut up.

“Without hope. Without witness. Without reward.”

DOCTOR: You know when grown-ups tell you everything's going to be fine and you think they're probably lying to make you feel better?

AMELIA: Yes.

DOCTOR: Everything's going to be fine.

“Sometimes the only choices you have are bad ones. But you still have to choose.”

AMY: You want to be forgiven.

DOCTOR: Don't we all?

“I've given up on that cuppa and opted for a life of abstinence.”

DOCTOR: It's not magic. It's a language. It's a different form of physics.

RUBY: Yes. Like magic.

“Ah, good. Scared keeps you fast. Anyone in this room who isn't scared is a moron.”

“Rule one. The Doctor lies.”

“I always rip out the last page of a book. Then it doesn't have to end. I hate endings.”

DOCTOR: What the hell are you doing!?

AMY: Changing the future. It's called marriage.
