“Gretchen Rubin has discovered a new framework for understanding ourselves and other people. When we know our Tendency, we can manage ourselves more effectively and reach our goals faster—and we can help others to do that, as well. As a researcher who has studied habits, addiction, and change for 20 years, I’m excited by the simplicity and power of The Four Tendencies as a tool for anyone seeking to make his or her life better. I am implementing this in my clinical programs to help people understand their Tendencies so they can change behaviors such as stress and emotional eating.”
