You've tried to build habits before. Maybe you started strong, then missed a day, then quit entirely, feeling like you lacked willpower. But willpower isn't the problem — the system is. This book offers a different approach: a realistic 30-day challenge focused on just one habit at a time. Drawing on behavioral science — including research from the American Psychological Association and leading habit researchers — Cora Banfield provides a clear, compassionate step-by-step system. You'll learn how to choose the right habit for your life, design it to be so small it feels effortless, stack it onto existing routines, and shape your environment to reduce friction. Simple tracking keeps you aware without obsession. When you slip (and you will), you'll know exactly how to reset without shame. By day 30, your new habit will feel automatic — and you'll have a repeatable method for building any habit you choose. Part of The Focused Life Library.
