Gretchen Rubin is one of today’s most influential and thought-provoking observers of happiness and human nature. She’s known for her ability to distill and convey complex ideas with humor and clarity, in a way that’s accessible to a wide audience. She’s the author of many books, including the blockbuster New York Times bestsellers The Four Tendencies, Better Than Before, and The Happiness Project. She has an enormous readership, both in print and online. Her books have sold over 3.5 million copies worldwide, in more than thirty languages (The Happiness Project spent two years on the bestseller list), and her weekly newsletter has amassed more than a million subscribers. On her top-ranking, award-winning podcast Happier with Gretchen Rubin, with more than 112 million downloads, she discusses happiness and good habits with her sister Elizabeth Craft.

In her long study of happiness and human nature, Gretchen Rubin realized that there’s no magic, one-size-fits-all solution to happiness—so she launched “The Happiness Project,” a diverse array of tools to help people become happier, healthier, more productive, and more creative, by taking happiness from the abstract to the concrete. She’s been interviewed by Oprah, eaten dinner with Daniel Kahneman, walked arm-in-arm with the Dalai Lama, had her work written up in a medical journal, and been an answer on the game show Jeopardy! In her work, she draws from cutting-edge science, the wisdom of the ages, lessons from popular culture, and her own experiences to explore how we can make our lives happier, healthier, more productive, and more creative.

Gretchen Rubin started her career in law and was clerking for Supreme Court Justice Sandra Day O’Connor when she realized she wanted to be a writer. Raised in Kansas City, she lives in New York City with her husband and two daughters.
