Reviews of Changeology

Self-help advice you haven’t heard before. Become more clever, more relaxed, more satisfied—and more realistic about how long it will take to make new habits stick.


This book promises a lot, and, in my view, Norcross has delivered: Changeology rises to the level of the best self-help books ever written…  Changeology will certainly connect with a great many people. The science is strong, the tools are practical, and the process can be tailored to each person’s needs. I wholeheartedly recommend this book as a stand-alone resource for those ready to change, for those working with professionals, and for professionals, family, and friends who are supporting change.

Norcross is the Billy Beane of personal-change gurus, using reams of psychological studies the way a sabermetrician uses baseball statistics. He’ll be the first to tell you that this scientific approach beats magical thinking.

I have rarely read one (self-help book) that I truly felt could bring real, meaningful change into a person’s life. But despite my wariness of the self-help genre, I found John C. Norcross’s Changeology to be one such book… for most of the kinds of change that people are already trying to make, Changeology will prove to be a wonderful source of assistance. It has an easy-to-follow formula based on credible research — and even this wary mental health practitioner found it helpful.

Changing a habit involves two things:  knowing how to change and knowing what to change.  This book, by a true master scientist of change, is the best book I know about the steps YOU can take to make and to sustain the changes YOU want to make.
— Mike Roizen, MD, co-author of the bestselling YOU series

John Norcross has accomplished a rare feat – translating 30 years of sophisticated psychological research into practical, understandable, doable steps that really work for changing behavior.  I recommend this book as a top choice to achieve important goals.

I just finished reading a new book that I think many of you will find valuable for your own lives and for your clients: Changeology: 5 Steps to Realizing Your Goals and Resolutions. The book is by the eminent and influential psychologist John C. Norcross (with Kristin Loberg and Jonathon Norcross). The book draws strength from decades of impressive scientific research, much of which Dr. Norcross conducted. He manages to translate this research into very specific steps within 5 major phases: contemplating change, planning for change, taking action, persevering through managing slips, and persisting over the long haul. The book is written in a style that is clear, user-friendly, and entertaining, recounting real-life adventures in change and sprinkling in relevant allusions ranging from classic to pop. An excellent and very useful book.
