Speaking of productivity systems, some time ago I read “How Square Defangs Difficult Decisions with this System — Here’s How.” The cheecky “Kombucha Scale” system turned out to be the Eisenhower Matrix:

You consider inputs according to a quadrant, where:

• things that are both urgent and important are done asap, but perhaps grudgingly;
• Important but not urgent, which is where the truly important work lies;
• urgent but not important, which is to be delegated, and
• the unfortunate neither urgent nor important items, which are deleted. These items don’t make it to your to-do manager.

But what about the other three quadrants? They do, in fact, have a place in your GTD system. Todoist has a great article on adapting their app to the matrix.

I struggled some time ago with using the Eisnehower Matrix with OmniFocus, but it’s only because I didn’t know what it was called. There are plenty of articles on it, notable this one from Effective Remote Work.
