In today's frenzied and wired world, we are obsessed with the idea of not "wasting time." But have we lost the silences and solitude so essential to our inner lives? A great deal of evidence suggests the value in wasting time, of letting the mind lie fallow for some periods, of letting minutes and hours go by without scheduled activities or intended tasks, of unplugging from the grid. In this vital investigation of the rush and heave of the modern world, Alan Lightman explores the technological and cultural origins of our time-driven lives. More importantly, he reveals the many values of "wasting time", for replenishing the mind, for creative thought, and for finding and solidifying the inner self. Lightman urges us, as both individuals and as a society, to break free of the idea that not a second is to be wasted and to discover that sometimes the best thing to do is to do nothing at all.
