The capacity to be alone, properly alone, is one of life’s subtlest skills. Real solitude is a powerful resource we can call upon–a crucial ingredient for a rich interior life. It inspires reflection, allows creativity to flourish, and improves our relationships with ourselves and, unexpectedly, with others. Idle hands can, in fact, produce the extraordinary. In living bigger and faster, we have forgotten the joys of silence, and undervalued how profoundly it can revolutionize our lives.
