Time management is a fallacy, we like to say. Time doesn't need you to "manage" it - it's been getting along just fine without you for billions of years. We can't manage time. But what we CAN manage is what we do with that time. And yet, the overwhelming evidence is that managers do NOT "manage what they do with that time." There's a shocking CHASM between our behavior in this area and our knowledge of what to do. In fact, Mark recently blogged on how busy everyone says they are, which irritates him. He looks at their calendars, and there's no EVIDENCE that they're busy. There are vast swaths of unscheduled time!
