I'm still at the point in my life where I view having kids as a hindrance to my independence.  As you said, it's selfish, but I also feel that eventually I'll reach a crossroads where I will actually want to make my life all about someone else.  From what I've seen of the world, a person can only live for themself for so long before the entire process of gratifying their own desires becomes redundant and meaningless.  Of course, that period of time varies, but I almost just know it will be sooner rather than later for me.
That's a great (if difficult) resolution.  Especially purposefully allowing yourself to be vulnerable -- that takes a kind of courage a lot of people don't have.
As far as my resolution, it is to live in the moment rather than always looking ahead to the future.  In high school I did everything for the sole purpose of college, but now that I'm here I've found myself living for the ever more distant future.  I realized that if I don't change my outlook, my life will be gone before I know it, which has depressed me sufficiently enough to take action.  The problem is that I don't really know HOW to live in the moment, so I'm making it up as I go.
