What is the 21 90 rule?
The rule is simple enough. Commit to a personal or professional goal for 21 straight days. After three weeks, the pursuit of that goal should have become a habit. Once you’ve established that habit, you continue to do it for another ninety days.
How long does it take to start a new habit?
It can take anywhere from 18 to 254 days for a person to form a new habit and an average of 66 days for a new behavior to become automatic.
What are the 4 stages of habit formation?
