I had a dream that I woke up from about 45 minutes ago. It was a dream that brought some insecurities to the surface of my mind. And then of course my mind was very actively worrying about those things, and I couldn't get back to sleep (and my mother snoring on the other side of the hotel room didn't help, either).
Happiness is calling your girlfriend at 4 a.m. (Vienna time), telling her your insecurities, and having her make you feel a million times better.
I still might not be able to get back to sleep, but it will be because I'm thinking about good things instead of bad things.
I'm having a great time on this trip, and I can't wait to get home.
