Many habit-formation strategies are familiar: monitor the behavior we want to change; hold ourselves accountable; schedule a specific time for an activity. Such strategies are important and powerful—but they’re familiar. In this talk, Gretchen Rubin will describe the insights into habit-formation that surprised her as she was writing her book, Better Than Before. For instance, she’ll explain why hitting a goal can undermine a habit, why getting treats (but not rewards) is important to mastering habits, and how her “Four Tendencies” framework can help us figure out how to set up habits for success.
