I don't make resolutions. I try to remind myself daily just to do things better--take that extra 20 minutes to read a book with my kids instead of checking emails, to push myself a little harder when I exercise, to make a point of eating healthier and living more mindfully. I don't succeed as often as I would like. But I plug away.
Nevertheless, lots of people do make resolutions. Hopefully, they're not broken already by January 3rd. Share what you'd like to do better for 2008.
