Last year, for a few weeks I had a goal of taking a photo a day and posting it on Flickr. It didn't last long, but one of my favorite photos was taken out of desperation to get a photo for one of those days:

Now, I'm not usually one to make New Year's Resolutions, but I think that, starting today, I'll try my best to take a photo a day. To increase my chances of this lasting more than a few weeks, I'll add that only 1 a week has to be good enough to post to my Flickr account.
Having such a goal keeps you shooting (and therefore practicing) daily. It also helps you look for subjects that you may otherwise miss. And lastly, it helps me get over my habit of skipping photo opportunities if it means I have to break my routine by pulling the car over or even worse -having to turn around! ;-)
So, there you go. This is my public announcement of my goal -perhaps that'll help me stick to it as well. And for those of you who are reading this, I highly recommend setting a similar goal for yourself.
