@adamprocter I agree with @jack. Brooks’s logical flaw is that he’s attributing decades old philosophies to today’s understanding of productivity. If you’ve studied the subject for any length of time or in any detail, you know that the discussions have since turned to effectiveness, not just “cranking out widgets” or saving minutes or hours. Time spent in OmniFocus, for example, is often spent reviewing and refocusing one’s efforts to make sure a project still means something, that it will have a positive outcome, or, indeed, whether it even needs to continue. OmniFocus (and other tools) is far less about saving time than it is about making sure one’s time is well spent.
