Look at the schedules of many executives, managers, and supervisors and you'll find plenty of meetings booked but two items missing:
1. Time for uninterrupted work on projects.
2. Time to think.
Unlimited open door policies doom the ability to have uninterrupted work time and so many offices promote the need to look busy that individuals are reluctant to take time to think. The thinker may appear to be "intellectual" and that is a lethal label for the ambitious in many companies since it is perceived as the opposite of bold decision makers and hard workers.
Taking time to think and setting aside meaningful blocks of time for uninterrupted work on projects are important but they won't be achieved unless the individual has the courage to make those choices.
And it is a wise organization that makes those choices easier.
