All must be corralled in one place and then processed using Allen’s core mantra of “Do it, delegate it, defer it”. If the action takes less than two minutes, do it there and then. If longer, you either hand off to someone else or defer it into your pending tray. Otherwise it is trashed or filed. The in-tray thereby becomes sacrosanct. You never put stuff back into “In”. Never.
On the web, for example, Getting Things Done (GTD) has gone supernova. Web and IT professionals have taken Allen’s core ideas and refined them into ever more effective tips called “life hacks”. Adherents swap these across a broad network of blogs, wikis and websites such as 43Folders.com – all amid a considerable amount of one-upmanship over who has the biggest and best system.
