Take care of yourselves and your loved ones. Do something wildly fun and daring. Smile at small kids and always wave if they wave at you. (Also, poke your tongue out at them as often as you can. You'd be surprised the joy you get from doing that.)
Wear odd socks.
2012; you were a good year. Admittedly I've had better, but the world didn't end so that's in your favour. Here's to 2013 being even bigger and greater.
