What you have learned from experience is worth much more than gold. If you have a house it may burn down. Any kind of possession can be lost, but your experience is yours forever. Keep it and find a way to use it.
To me, when one is writing sometimes about a very specific subject with very specific people, I feel like if that story doesn't cross over, it's not working. That's very beautiful to me, to be sitting in Berlin and there's an actor reading my book in German. I don't even know what's going on, except I know to feel my own rhythms in another language and say, "If this is going well, I think everyone should laugh around now. " Then maybe there's laughter, and for me, it reminds me of how story can move around the world.
