I’ve been researching mindfulness since the early 1970s. New findings emerge from our lab and others each year, showing what a powerful factor mindfulness is with respect to our health, happiness, and effectiveness. Everything we do, we do mindfully or mindlessly, which suggests that it can be one of the most important drivers of our well-being. It’s easy to understand why someone might decide to skip the gym, eat a donut, or fail to finish an assignment. But what sense does it make to choose to be mindless?
