I'm probably gonna do 50% Harry Potter, 50% Doctor Who... Oh well! 

1. "'Give her hell from us, Peeves.' And Peeves, whom Harry had never seen take an order from a student before, swept his belled hat from his head and sprang to a salute as Fred and George wheeled about to tumultuous applause from the students below and sped out of the open front doors into the glorious sunset." (HP 5)

2. "Let us step into the night and pursue that flighty temptress, adventure." (HP 6)

3. "But you know, happiness can be found even in the darkest of times, if one only remembers to turn on the light." (HP 3)

4. "If you want to know what a man's like, take a good look at how he treats his inferiors, not his equals." (HP 3) 

5. "Do not pity the dead, Harry. Pity the living, and, above all, those who live without love." (HP 6) (I think)

6. "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 and make them unimportant." – The Doctor

7. "Books! The best weapons in the world!" - Tenth Doctor

8. "You don't just give up. You don't just let things happen. You make a stand! You say no! You have the guts to do what's right, even when everyone else just runs away" – Rose Tyler

9. "Fear doesn't have to make you cruel or cowardly... fear can make you kind. It doesn't matter if there's nothing under the bed or in the dark, so long as you know it's ok to be afraid of it. So, listen. If you listen to nothing else, listen to this. You're always going to be afraid, even if you learn to hide it. fear is like... a companion. A constant companion, always there. But that's ok. Because fear can bring us together. Fear can bring you home" - Clara Oswald

10. "Sometimes, the only choices you have are bad ones, but you still have to choose." 12th Doctor
