An interview with Charles Duhigg, reporter for The New York Times and author of The Power of Habit: Why We Do What We Do in Life and Business . "Every habit has three components. There’s a cue, which is like a trigger for the behavior to start unfolding, A routine, which is the habit itself, the behavior, the automatic sort of doing what you do when you do a habit. And then at the end, there’s a reward. And the reward is how our neurology learns to encode this pattern for the future."
