“Watch it, your sanity. Watch the line. What I don’t say is that the line is hardly there. It’s as blurry and fluid as the slope of the shore, from beach to the shallows to water over your head to the open sea. And I’m not really supposed to believe in that spectrum…..But we’re all there on the slope. I think the difference is whether you’ve maneuvered yourself into a position where your head’s above the sea.”
