@Folke: You make very good points as always. I too spend the majority of my time making gut-based decisions in the moment. Why? Because priorities change so rapidly from moment to moment. What you thought was the most important thing to work on in the morning may have changed dramatically when the morning arrives. WIth that said, I do still believe in the power of time blocking when you have a major deadline on a project. But the moment-to-moment decision-making process is at the heart of GTD and why it works so well! Cheers and best wishes!
