resolutions?

So the year is waning and many people are thinking about their New Year resolutions.
I've never been very good at making, or keeping, them, so most years I figure, why bother?
I do, however, always admire those people who make resolutions and actually work hard to achieve their various goals.
There are those who diligently diet and exercise; others who finally quit smoking; or perhaps they head back to college or change careers.
There are so many areas where I could resolve to change my life that it's hard to pick just one.
But I'm trying to narrow it down before New Year's Day. Perhaps it won't be so much a formal resolution, as simply a resolve to begin to make a difference in at least one area.
Like I said, there are many from which to choose.
I wonder if others are having the same dilemma?
