'I love Gretchen Rubin - she helps me understand both myself and the people around me' Cathy Rentzenbrink, 'Obliger' and bestselling author of The Last Act of Love During her investigation to understand human nature, Gretchen Rubin realised that by asking the seemingly dry question 'How do I respond to expectations?' we gain explosive self-knowledge. She discovered that based on their answer, people fit into four Tendencies: Upholders, Questioners, Obligers, and Rebels. Our Tendency shapes every aspect of our behaviour, so using this framework allows us to make better decisions, meet deadlines, suffer less stress, and engage more effectively. More than 800,000 people have taken her online quiz, and managers, doctors, teachers, spouses, and parents already use the framework to help people make significant, lasting change. The Four Tendencies hold practical answers if you've ever thought... - People can rely on me, but I can't rely on myself - How can I help someone to follow good advice? - People say I ask too many questions - How do I work with someone who refuses to do what I ask - or who keeps telling me what to do? With sharp insight, compelling research, and hilarious examples, The Four Tendencies will help you get happier, healthier, more productive, and more creative.
