Hi Gretchen, I believe it does take 21 days to change or create a habit although I think the statement should be rephrased to say it takes approximately 21 days of consistent daily behaviour combined with belief, faith, determination and emotional leverage or sincere desire to succeed to form new habits.
If youâd like a little help with keeping a habit, Kaizan has a good tip for helping habits not break down: How to Make Sure That Nothing Gets Between You and Your Good Habits. In the comments to that post, someone cites an often-repeated piece of information that it takes 28 days to form a habit. Iâve heard this more than once, but never heard that it was based on any reliable research.
