The problem with New Year's resolutions - and resolutions to 'get in better shape' in general, which are very amorphous - is that people try to adopt too many behavioral changes at once. It doesn't work. I don't care if you're a world-class CEO - you'll quit.
There are a lot of dedicated people out there that don't get the recognition that we get, but they're as important as the people that are sitting in the vehicle.
