Forming a new habit (or breaking an old one) is highly personal, so it's hard to nail down a universal timeline or strategy. That said, researchers have a pretty good framework for how habit formation unfolds in the brain, by way of a three-step process called the Habit Loop. And understanding the Habit Loop can help guide us towards building better habits. *References: 1. Luciani, J. Why 80 Percent of New Year’s Resolutions Fail. Retrieved from US News & World Report 2.
