stickKing to my resolutions

I just created a "commitment contract" to exercise 5 times a week at stickK.com, a site recently launched by Yale Professors Dean Karlan and Ian Ayres. In short, stickK lets you commit to any goal you can think of, with the option to donate money to a charity (or anti-charity!) if you lose. I didn't put any cash down, but they claimed that even just formalizing a commitment should help. We'll see how it goes.
