My favorite story was about a boy who'd live forever but his eyes were heavy with the weight of all he'd seen. / The opening lines from the Doctor Who episode "A Town Called Mercy" for Merlin. This fits a little too well.
The way I see it, 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 necessarily spoil the good things or make them unimportant.
My wisdom comes from experience. My passion comes from pain. My confidence hides my insecurities. My weakness makes me stronger. My past does not define me. My strength is an illusion. My calm makes a storm. My innocence is not ignorance.
