"People who have only good experiences aren't very interesting. They may be content, and happy after a fashion, but they aren't very deep. It may seem a misfortune now, and it makes things difficult, but well--it's easy to feel all the happy, simple stuff. Not that happiness is necessarily simple. But I don't think you're going to have a life like that, and I think you'll be the better for it. The difficult thing is to not be overwhelmed by the bad patches. You must not let them defeat you. You must see them as a gift--a cruel gift, but a gift nonetheless."
— Peter Cameron (Someday This Pain Will Be Useful to You)
