Today I sit down with New York Times bestselling author Gretchen Rubin to find out what happened when she asked a large number of people one singular question: how do you respond to expectations?The answers led Gretchen to an epiphany — that four distinct human tendencies intrinsically underlie how each and every one of us approach our interior and exterior lives. Understanding your tendency changes how you perceive yourself and others. It informs better communication. It provides the structure to create better habits. And ultimately it serves to support the purposeful pursuit of the personal and professional life experience you most seek.This is the terrain of today's exploration.A member of Oprah’s Super Soul 100 who was named one of the Most Creative People in Business by Fast Company, Gretchen is an über-author who has sold over 3 million books on the subject of habits, happiness and human nature. You may know Gretchen from her wildly popular blog, her runaway bestseller The Happiness Project*, or from one of her other many titles such as Happiness At Home* and Better Than Before*. An exploration of the aforementioned architecture of human motivation, Gretchen's new book is entitled The Four Tendencies: The Indispensable Personality Profiles That Reveal How To Make Your Life Better (and Other People's Lives Better, Too)*.When she isn't writing, Gretchen hosts the wildly popular Happier With Gretchen Rubin podcast (along with her sister, TV writer Elizabeth Craft), awarded “Best Podcasts of 2015” honors by iTunes and named one of the “Best Podcasts of 2016″ by the Academy of Podcasters (I didn't even know podcasting had an academy, but there ya go).In addition, Gretchen is the creator of Better, a free mobile app that connects you with others to harness the Four Tendencies and create a better life.This conversation is jam packed with super helpful amazing takeaways.A former editor-in-chief of the Yale Law Journal who clerked for Supreme Court Justice Sandra Day O'Connor, we track Gretchen's leap from high-powered lawyer to pursue a career in writing.We talk about how her revelation about “expectations” led to The Four Tendencies, then unpack the specifics, tracking how these core archetypes can better inform our habits, our understanding of others and how we structure our professional and personal lives.I learned a lot about myself in this one.Enjoy!Rich
