Okay, so maybe it's not at the TOP of your list. But if you don't have a will (and powers of attorney, and a living will), making one could be your best new year's resolution! These instruments make it possible for your family members to know and respect your wishes regarding:

your emergency and end-of-life care
how your property is distributed
who will make important decisions for you in the event you cannot
how your children (and other loved ones) will be cared for and provided for financially, and according to what rules

It's not as tasty as brownies, but that's a lot of good stuff in one item on your to-do list!
