• Distinguishes between goal-based and identity-based habits.
• Explains the variability in time it takes different individuals to form the same habit.

Providing actionable steps for habit formation.

• Outlines explicit steps for forming habits based on neuroscience and psychology.
• Offers a program that includes getting sunlight, exercising, and managing caffeine intake to increase the likelihood of forming new habits.

Strategies for breaking habits and the role of reward prediction error.

• Understanding the biological mechanisms behind breaking habits, including long-term depression.
• Discusses the concept of reward prediction error and its significance in habit breaking.

Introducing a phase-based system for categorizing habits throughout the day.

• Phase one (0-8 hours after waking) is action-focused and ideal for overcoming limbic friction.
• Phase two (9-14 hours after waking) supports relaxation and habits requiring less conscious override.
• Phase three (16-24 hours after waking) is for deep rest and consolidation of learning.

Describes a 21-day program designed to instill new habits.

• Aim to perform 6 new habits daily for 21 days, expecting to complete 4-5.
• After the 21-day period, assess which habits have become reflexive and potentially add new habits.
