Posted this over in the "How was your commute" thread too, but oh well.

...
Like the OP today is my last commute of the year. My previous best year was driving to work something like 75 times, and riding about 2400 miles.
For this year I set a goal of riding 4000 miles and driving to work fewer than 50 times. I also set a goal of losing 50 pounds. I met all of my goals, logging about 4250 miles and only driving to work 25 times.
I also lost 50+ pounds. Most of the weight loss was due to my dietary changes, though. But the increase in riding certainly helped. When I hit the 50 pound weight loss goal last July I rewarded myself with a nice new carbon-framed bike.
It was a pretty good year in this regard.
