To make the journey without falling deeply in love, you haven't lived a life at all. You have to try, because if you haven't tried, then you haven't lived
When you start talking about the known knowns and the unknown unknowns, you're thrown into a crazy meta-level discussion. Do I know what I know, do I know what I don't know, do I know what I don't know I don't know. It becomes a strange, Lewis Carroll - like nursery rhyme.
