New Year's Resolutions

I've never been one of those to make New Year's Resolutions, but after having such a great 2009 and meeting so many of my goals - I've decided to make a go of it.  So here are a few:

• I really want to run that half marathon.  This year.  I will do it.
• I want to get to my goal weight.  I fear that I will bounce back to about where I am - that my body just isn't very comfortable any lower than this, but I would like to at least get there.
• But most of all - I don't want to go back.  That scares me.

What are some of your resolutions?
