Commit for 21 Days to Form a New Habit
The rule implies that it takes 21 days to build or break a habit and 90 days to create a lifestyle. It’s so much easier to build a daily habit than, let’s say, one you practice every other day.
In fact, it’s exponentially easier. So, if you focus on doing your new habit for 21 straight days, the effort is a fraction of the effort you’d have needed to perform the same habit every other day.
Thanks to daily practice, you train your mind to recognize the habit loop. There are no holes in your discipline. Your brain doesn’t get confused about a habit trigger. The repetition is continuous, so the lesson from day #1 is reinforced on day #2 and so on.
“We are what we repeatedly do. Excellence, then, is not an act, but a habit.” – Will Durant
