I'll go first:
“Why does the third of the three brothers, who shares his food with the old woman in the wood, go on to become king of the country? Why does James Bond manage to disarm the nuclear bomb a few seconds before it goes off rather than, as it were, a few seconds afterwards? Because a universe where that did not happen would be a dark and hostile place. Let there be goblin hordes, let there be terrible environmental threats, let there be giant mutated slugs if you really must, but let there also be hope. It may be a grim, thin hope, an Arthurian sword at sunset, but let us know that we do not live in vain.”
-Terry Pratchett
"If you stray from the well trodden path, tread your own path for others to follow"- Paul Stewart
(I actually used this as my grad quote in my yearbook when I graduated high school).
"Self love, my liege, is not so vile a sin as self-neglect."
William Shakespeare, Henry V
The more you try to crush your true nature, the more it will control you. Be what you are. No one who really loves you will stop.
-Cassandra Clare
I hope someday, somebody wants to hold you for twenty minutes straight. They don't pull away, they don't look at your face, and they don't try to kiss you. All they do is wrap you up in their arms and hold on tight without an ounce of selfishness to it. I hope you become addicted; I hope you become addicted to saying things and having them matter to someone.
-Sara Bareilles
