Note to self: being Kurt's son, being an ex-mental patient, getting into Harvard, having written a book, and being a doctor are all things that in and of themselves do not make a life. If you lean on them too hard, you'll find that there's not much there. But if you add up a lot of things that aren't in and of themselves enough, it almost starts to add up to something.
Everything is shown up by being exposed to the light, and whatever is exposed to the light itself becomes light.
