Best quote from Building Habits: The Science of Change and the 21-Day Myth
When you understand the actual mechanics of change, you realize that 'failing' on day twenty-two does not mean you are broken; it just means your brain is still in the middle of a very physical construction project.

How to Build Good Habits
Frequently Asked Questions
The idea that it takes exactly twenty-one days to form a habit is a total myth with no empirical evidence behind it. While this rule is popular, clinging to such a rigid window often leads to frustration when behaviors do not become effortless. Modern behavioral research suggests that the timeline for habit formation is actually much more variable and complex than the three-week rule implies.
Recent studies in neuroscience indicate that the average time for a behavior to reach automaticity is closer to sixty-six days. However, this timeline is highly individual and depends on the complexity of the habit. Research shows the process can range anywhere from eighteen days to more than two hundred and fifty days, as your brain undergoes a physical construction project to rewire itself.
Understanding the actual mechanics of change allows you to stop blaming your willpower and start focusing on your strategy. When you realize that habit formation is a physical process in the brain, you understand that 'failing' early on doesn't mean you are broken. Moving away from 'white-knuckling' and discipline alone helps you navigate the variable timeline of brain plasticity more effectively.
