and nurture its growth. Silicon Valley legend BJ Fogg, pioneering research psychologist, founder of the iconic Behavior Design Lab at Stanford, and one of Fortune's '10 New Gurus You Should Know', has cracked the code of habit formation. Based on twenty years' research and used by over 60,000 people, his method reveals that the key to changing behaviour is the opposite of what you've always been told. It isn't about willpower. By focusing on what is easy to change, not what is hard; focusing on what you want to do, not what you should do, you'll discover that creating happier, healthier lives can be easy, and surprisingly fun. BJ Fogg is Tim Ferriss’s mentor and a bona fide Silicon Valley legend. His model is a fundamental breakthrough in understanding why people change and why they don’t.
