Why do most people fail to keep their New Year's resolutions?

Most people fail to keep their New Year's resolutions due to unrealistic expectations and lack of specific planning. Many resolutions are broad or overly ambitious, leading to feelings of overwhelm and discouragement. Additionally, a lack of accountability and support can make it difficult to maintain motivation over time. Lastly, habits take time to change, and without consistent effort and reinforcement, individuals often revert to their old behaviors.
