Habit building — 21 days vs. 66 days
To form a habit takes 21 days and has been misinterpreted often for many years.
All of my previous challenges are around 35 days long.
If I don’t enjoy a challenge in the first 1–2 weeks, I leave it for some time, especially if it’s not helping.
The notion of developing a 66-day challenge is related to Dr. Maxwell Maltz.
