What does it really take to change a habit? Charles Duhigg, journalist and author of The Power of Habit, joins us to explore how our understanding of habits has evolved and why lasting change may start with changing how we see ourselves. From the “habit window” and keystone habits to habit chaining and identity shifts, we challenge long-held assumptions about willpower and explore how small changes in behavior and perspective can lead to lasting transformation.
