Why are we so obsessed with productivity? Horticulturist Rebecca McMackin (who wants people to let their lawns grow wild) and author Catherine Price (who wrote a book about the power of fun) come together to discuss the relief of giving up control. From growing milkweed to taking up unproductive hobbies, they dig into the benefits of rest — and why doing something for its own sake shouldn't need defending. (This conversation is part of "TED Intersections," a series featuring thought-provoking conversations between experts navigating the ideas shaping our world.)
