Teddy Roosevelt once said that nothing is worth doing “unless it means effort, pain, and difficulty.” And to that bestselling author Greg McKeown says, “Baloney!” There’s no denying that hard work often leads to positive results, but it can just as easily lead to exhaustion, apathy, and burnout. In his script-flipping new book, “Effortless: Make It Easier to Do What Matters Most,” Greg asks: “What if instead of pushing ourselves to — and in some cases well past — our limit, we sought out an easier path?” And in this easy-going conversation with author Jon Acuff, he shares some of the answers he’s come up with.

Modern life has not been easy on our brains. Average IQ scores rose steadily throughout the last century. Now they appear to be leveling off. The problem, according to neuroscientists, may be that we have reached our neurobiological limits. Our brains simply can’t work any harder. Luckily, science writer Annie Murphy Paul has a solution. In her bold new book, “The Extended Mind: The Power of Thinking Outside the Brain,” she draws on a wealth of scientific research to show that we’re smarter when we get out of our heads. By offloading our memories onto our phones, making decisions based on our bodily sensations, using tactile tools to solve abstract problems, drawing inspiration from our surroundings, and arguing with our friends, we can access intelligence that exists beyond the confines of our craniums. In this episode, Annie explains how to do it.
