Atomic Habits meets Think Like a Monk in this profound guide to lasting change from behavior coach and host of the hit podcast The One You Feed. Weaving together behavioral science with timeless wisdom, Eric Zimmer reveals how to stop fighting yourself and start moving forward.

More than 30 years ago, Eric Zimmer faced a life-altering battle with heroin addiction that left him homeless and facing prison—a turning point that sparked his search to understand how profound change happens, and how we can chart sustainable paths forward while honoring both who we are and who we hope to become.

How a Little Becomes a Lot starts with a radical premise: your mind has a mind of its own. Each day, it pulls you in countless directions—toward what you value most, what you desire now, away from what you fear, and toward what feels comfortable. Real, lasting change happens when you stop trying to strong-arm this complexity and instead learn to work with it, one small choice at a time.

Zimmer's motto is simple: little by little, a little becomes a lot. Personal transformation isn't about superhuman willpower or heroic feats of character. It's not a watershed or an epiphany; it's the result of the little decisions to do A instead of B, to say yes instead of no. These tiny shifts create powerful momentum.

Drawing on sources from Zen Buddhism to modern psychology, Zimmer offers practical wisdom you can use today:

• A path to align your daily actions with your core values
• Tools that quiet self-criticism and build the kind of self-compassion that actually works
• Small, achievable practices that create momentum when you feel stuck
• Ways to find balance in a world that pushes extremes

These “Wise Habits” blend outer behaviors that improve health and well-being with inner attitudes that bring more peace and clarity to everyday life.

Whether you’re feeling stuck, trying to change a specific habit, or seeking a more fulfilling life, How a Little Becomes a Lot will work for you. And by the end, that won’t feel little at all.
