A large amount of our daily behaviours tend to be motivated by what we see as unconscious and automatic habits that have in many ways been ingrained in us since childhood. When we set a New Year's resolution though, that is a very deliberate action, a very conscious thought. It can be really difficult to integrate this conscious and deliberate thing we want to achieve into our daily lives because they are so hard to integrate. This explains why achieving our New Year's resolutions is not just about pure determination, it's not just about how much you want it.
