Starting a new habit is as traditional part of a New Year's celebration as eating black-eyed peas. This year, consider starting a journal. It's a great way to mark accomplishments and things you're grateful for (or things you would rather avoid in the future). I have been keeping an online journal for the past two years and it's been very helpful for finding mistake patterns, as well as logging accomplishments - which is very helpful as you enter the annual review process.
Use paper, a word doc, or my favorite - the 3Minute Journal app (disclaimer: I have been involved in building the app). Plan to set aside a couple of minutes at the end of each weekday (or every day) to write down the most significant event that happened and answer a few questions about it. Within a month or so, you'll have a rich repository of data about yourself that you can use to track your inner work life.
