I don't make New Year's resolutions. Doing so never has worked for me. Instead, I take a different approach.
I know that I should do something. It needs to be done. Whether for myself, for someone else, or for my institution. Maybe it's simply the right thing to do. So why wait for a new calendar before acting?
I try to make daily resolutions. Perhaps I have to complete a specific task. I may want to make significant progress on a long-term project. More than anything, I try to do things at least a bit better than the previous day.
