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.
On average it took 66 days for the participants to start a habit. (Thatâs March 6 if you are attempting a New Yearâs resolution). Another interesting result of the study was the amount of variation. Even though 66 days was average, the number of days for habit formation varied wildly from 18 days to 254 days.So, there really isnât a magic number, just an average. There was also variation in how strong the habit became, based mostly on the type of habit.ven though 66 days was average, the number of days for habit formation varied wildly from 18 days to 254 days.
