A good concise reference method for organizing calendars and tasks. It sounds a bit mundane, but good organization has far reaching consequences. This summary text is short on examples, so it isn't immediately obvious precisely how to implement some of the ideas, or how to resolve the contradictions that will arise in implementation. Perhaps David Allen's full text covers all of that, but that research will have to wait for another day. Recommended reading for everyone who feels overwhelmed by their work or home schedules and tasks.
