“Happiness is the most natural thing in the world when you have it, and the slowest, strangest, most impossible thing when you don't.

So while you're saying all of these stupid, boring things I'm imagining what it would be like to cut you open and see what you've got in there.”

“Each life has a different purpose, and some people can find their purpose more easily than others. The key, the most important thing you can ever know, is that whatever your purpose is, that's not your only choice""No matter why you're here, no matter why any of us are here, you're never tied down to fate. You're never locked in. You make your own choices, Kira, and you can't let anyone ever take that away from you.”
