One of the things that works for me in terms of keeping up w/my resolutions is putting them out in the public view.  Here are mine:

1. Perform at least 1 Million pounds of weightlifting exercise (not all at once)
2. Run 300 miles
3. Lose 14 pounds
4. Run at least 1 sprint triathlon
5. Release one open source project
6. Finish writing book 3 of my paleo-fantasy trilogy
   
7. Attend at least 12 networking/tech meetings
8. Spend at least 100 hours on personal s/w projects
9. Get at least 2 characters to level 12 in Dungeons and Dragons Online (this way, I’m obliged to have some fun too!)

And, since I wrote it, I’ll use Bellygraph to track my progress, for the ones where it makes sense.
