I saw this article posted by David Allen on Twitter. It intrigued me because I often here people summarize GTD as nothing more than "list-making." But it's more than that and yet, that's all it is. I think it's the power and simplicity of a checklist that makes it so important. But we often think that a checklist can't be the answer to my busyness. If that's you, I recommend reading The Checklist Manifesto.
