Unbroken blocks for think time

"First, create unbroken blocks for individual think time, preferably during the most lucid time of day; these pockets of quietude might be only ninety minutes, but even the busiest executive must do them with regularity. Second, create chunks of deliberately unstructured time for people and the inevitable stuff that comes up. Third, engage in meetings that matter, making particular use of carefully constructed standing meetings that can be the heartbeat of dialogue, debate, and decision; and use some of your think time to prepare and follow up."
