Have you heard about Shultz hour? It is a method advocated by Shultz, a secretary of the state in the 1980s. Shut down for an hour. Think about the strategic aspects of the job. This activity will help you to prevent wasting years by not being able to waste hours.
There are organizations which have enforced an hour of focused activity by requesting everyone working out of a location to avoid phones. This simple change in the daily work shoots up the productivity of the work force. This hour of focused activity is indeed Shultz hour.
Some people engage in an hour or more of activity. These could be walking, running or working out. If you analyze this behavior, it is also a variant of Shultz hour.
