Mike literally tracks every hour of his day, down to quarter-hour increments, on a spreadsheet. He wants to ensure that his attention is focused on the activities that matter. “It’s so easy to just come in and spend your whole day on e-mail,” he warned. On the sample spreadsheet he sent me, he allots himself only ninety minutes per day for e-mail. The day before we last spoke he had only spent forty-five. This is a man who is serious about doing what he does really well.
