When writing about habits for her last book, Better Than Before, Gretchen Rubin stumbled on the biggest discovery of her life the Four Tendencies.

The Tendencies describe how a person responds to motivation, and how that affects family dynamics, happiness, work, and organisations.

Since introducing the idea to audiences, she has been overwhelmed by questions from people who want to know how they can use the framework in their own lives.

More than 600,000 people have taken her online quiz and teachers, parents, managers, spouses, coaches, doctors and healthcare providers are already using the framework to make significant, lasting change in people's lives.

The Four Tendencies will help you answer questions like:

• Why won't my spouse take out the trash? 
• How can I manage my employees so they meet deadlines more consistently?
• Why does my bright child refuse to do his/her homework?
• Why won't my patients take their medicine?

The Four Tendencies is the authoritative guide that will allow you to understand not only yourself better, but those around you.
