The new year is always a good time to reflect. It's also a great time to take a look back at the work we've done and what we've learned. Going back through your previous years images is no easy task, but it will help you see the progress you've made. You'll also see all the work you've put into honing your craft over the year.
This may also be a good way to make sure your images are organised in a way that makes them easy to go through. Having your folders labeled properly will make it much easier when trying to find specific images later.
