Your GTD system works because each list and category has a clear purpose.

When those edges are clean, it is easy to see what to do, what to track, and what to ignore.

When they blur, lists lose meaning and your system becomes inefficient.

What Are Hard Edges?

In Getting Things Done, David Allen explains that each category, such as Next Actions, Projects, Waiting For, Agendas, Reference, and Someday/Maybe, should remain clearly distinct.

Each represents a different type of agreement with yourself about:

  • What something means
  • When you will see it
  • How you will engage with it

Why Hard Edges Matter

Hard edges create clarity, and clarity supports engagement.

  • You see only what is relevant in the moment
  • Decisions require less thinking
  • Lists stay trusted and actionable
  • Reviews become faster and easier

Reflection

  • Which of your lists has started to blur?
  • Where would restoring a clear edge create immediate clarity?
