The Habit Stacking Method

Bonnie Buzzell is a behavioral design researcher, writer, and speaker whose work focuses on the practical application of habit science to everyday life. With a background in cognitive psychology and organizational behavior, she has spent over a decade studying the mechanisms through which ordinary people create extraordinary, lasting change—not through heroic effort, but through the deliberate design of their daily environments and routines.

Before becoming a full-time author and educator, Bonnie spent eight years as a behavioral coach for mid-career professionals navigating major transitions, from career shifts to health crises to personal reinvention. It was through this work that she discovered a persistent pattern: the clients who succeeded in making lasting changes were rarely the ones with the most discipline or the most ambitious goals. They were the ones who found ways to connect new behaviors to existing rhythms—who built their changes into the structure of their lives rather than trying to bolt them on top.

Bonnie's writing has appeared in *Psychology Today*, *The Greater Good Science Center*, and *Behavioral Scientist*, where she covers topics ranging from habit formation and willpower depletion to environmental design and the psychology of motivation. She has delivered keynote talks and workshops to organizations including Microsoft, the U.S. Army's Comprehensive Soldier and Family Fitness program, and the International Positive Psychology Association. Her work bridges the gap between academic research and everyday practice, translating studies from institutions like Stanford, Duke, and University College London into actionable strategies that anyone can implement.

*The Habit Stacking Method* is her first book. She lives in Portland, Oregon, where she maintains her own habit stacks with varying degrees of consistency—and considers that variation itself the most important habit of all.
