I highly recommend spending a week riding the transsiberian across Russia. There are very few opportunities to reflect with nothing to do or that you can do for that long. The food is passable, the scenery is incredible, the people are nice, and the beds are unexpectedly comfortable.
I read war & peace, and found it enjoyable. I made more progress on research, both immediate code and long term priorities, than I have for quite a while, and I feel well rested and ready to jump in to 2014.
