"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."
"We're all stories in the end. Just make it a good one, eh?"
"I'm not running away from things, I'm running towards them."
"The way I see it, time is not the boss of you. You are."
