Willpower and self-discipline aren't the key factors for successful behavior change. Habits are deeply embedded in our subconscious and run automatically without conscious control. Our brain constantly seeks ways to save energy, and habits are an efficient way to do this. Instead of relying on willpower, we should focus on changing our environment and triggers.

Our environment plays a crucial role in forming and maintaining habits. Specific places, times, or emotional states can trigger habits. Wood demonstrates how we can consciously design our environment to promote positive habits and reduce negative ones, such as keeping healthy snacks readily available or deliberately putting away our phones.

Establishing a new habit requires time and patience. Wood emphasizes the importance of repetition to strengthen new neural connections in the brain. The more often we repeat an action in a specific context, the more automated it becomes. It's about integrating new behaviors into our daily routine and repeating them until they become automatic.
