‘How long does it take to form a new habit?’
People often ask this question, but it isn’t useful. Habit formation depends less on duration and more on frequency. In one week, a person who does 10 push-ups everyday will get much farther than somebody who only pushes-up 10 times during the weekends.
When it comes to making new habits, a more useful question is ‘how often does it take’.
Yet, the question of ‘how long does it take’ is still useful, when we speak about breaking habits.
When it comes to breaking habits, duration makes sense. If you want to break a habit of snacking on potato chips, each day you go without snacking on chips is a small step towards breaking the habit.
Think of forming habits in terms of reps. Think of breaking habits in terms of duration.
