We are all worried about wasting time. Especially in the West, we have created a frenzied lifestyle in which the twenty-­four hours of each day are carved up, dissected, and reduced down to ten minute units of efficiency. We take our iPhones and laptops with us on vacation. We check email at restaurants or our brokerage accounts while walking in the park. When the school day ends, our children are overloaded with “extras.” Our university curricula are so crammed our young people don’t have time to reflect on the material they are supposed to be learning. Yet in the face of our time-driven existence, a great deal of evidence suggests there is great value in “wasting time,” of letting the mind lie fallow for some periods, of letting minutes and even hours go by without scheduled activities or intended tasks.
