GirlyGirlSebas, I basically started with a New Year's resolution, but one reason I had a feeling it was going to "take" this time was that I actually started on December 29, 2008. In the past, I would have used those three days as an excuse to eat everything in sight. This time, I was jazzed to get started, so I started a little early.
New Year's is actually my favorite holiday--something about the idea of closure and renewal, and starting a shiny new year in which we're all perfect, at least initially.
Best wishes to you in 2011!
