Modifying an existing habit is more effective for habit change than breaking a habit.

“But for a bad habit, a habit that we want to extinguish, our nomenclature is incorrect. We often talk about breaking a bad habit, but because that neural pathway exists in our brain, I I've smoked for 20 years. I can't just extinguish that those neural connections. What I need to do is instead of thinking about breaking that habit or extinguishing it, I have to think about changing that habit.”
