One of my all-time favourite productivity authors is Leo Babauta of Zen Habits.

He has this excellent idea about setting New Year's goals, which is: don't do it. At least not until you've taken stock of everything that happened over the last year.

He has a process that he calls the "Sacred Bow" (rhymes with cow) - which is to look at each month over the last year and simply note the major events that occurred.

Then look at all of the lessons you learned and all of the accomplishments that you achieved over the last year.
