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.
After all, forming new habits never goes out of style, whether weâre talking about New Yearâs Resolutions or just a few changes you think it might be time to make. The 21 Days Myth: According to a piece James Clear wrote for the Huffington Post, the origins of the myth that it takes 21 days to form a new habit can be traced back to the 1950s. Plastic surgeon Maxwell Maltz noticed that when he performed operations like nose jobs on his patients, it took them about 21 days to get used to seeing their new face.
