How Long Does It Take to Build a New habit?

One of the most common questions I hear is, “How long does it take to build a new habit?” But what people really should be asking is, “How many does it take to form a new habit?” That is, how many repetitions are required to make a habit automatic?

There is nothing magical about time passing with regard to habit formation. It doesn’t matter if it’s been twenty-one days or thirty days or three hundred days. What matters is the rate at which you perform the behavior. You could do something twice in thirty days, or two hundred times. It’s the frequency that makes the difference. Your current habits have been internalized over the course of hundreds, if not thousands, of repetitions. New habits require the same level of frequency. You need to string together enough successful attempts until the behavior is firmly embedded in your mind and you cross the Habit Line.
