A key element of productivity consists of knowing when to engage and when to disengage.
We cannot function well as hermits and yet we need quiet time in which to collect our thoughts. The latter activity is often scorned as wool-gathering or goofing off. In an action-oriented environment, it can be an act of bravery to declare the need for additional thought.
Much is intangible. We shuffle tasks and search for poetry in our work. I suspect that it usually lurks in the balance between action and analysis and between engagement and disengagement.
