“You might think and be so marvelously right about praise that you open your door one day and the day walks in and stays for years.”

“When you wake up, think about winning the day. Don't worry about a week or a month from now -- just think about one day at a time. If you are worried about the mountain in the distance, you might trip over the molehill right in front of you. Win the day!”

“If you even think about asking Harry Potter for an autograph, your day ends right now.”

“Why will I bury you? So that one day I might disturb your grave.”

“When you run with the Doctor, it feels like it'll never end. But however hard you try you can't run forever. Everybody knows that everybody dies and nobody knows it like the Doctor. But I do think that all the skies of all the worlds might just turn dark if he ever for one moment, accepts it. Everybody knows that everybody dies. But not every day. Not today. Some days are special. Some days are so, so blessed. Some days, nobody dies at all. (In the library, the Doctor walks back to the TARDIS. He stops, looking at the doors. Then he raises his hand, and stands there poised like that for a long moment. Finally he snaps his fingers. The doors open. He smiles slowly and walks in, joining Donna. Then he snaps his fingers again, and the doors close. River's voice continues over this.) Now and then, every once in a very long while, every day in a million days, when the wind stands fair, and the Doctor comes to call... everybody lives.”

“I love being inside you, and touching your face, and opening my eyes so I know it's really you. And after we're finished, I go into a fever thinking about a day when I can leave myself inside you. When I'll steal the soap and turn off the water so I stay there... inside you... part of you.”
