Rockefeller's job was to make good decisions, which required quiet time alone to think through problems. His productivity came from mental work, not physical labor.
46% were in agriculture, and 35% were in crafts and manufacturing, according to economist Robert Gordon.
Today, 38% of jobs are managerial, professional, or decision-making roles, and 41% are service jobs that rely on thought processes as much as actions.
Workplaces often expect visible labor, like typing or clicking, because they are anchored in the old model where productivity was tied to physical action, not mental work.
A Stanford study found that walking increases creativity by 60%.
Productivity growth might be lower because workplaces expect knowledge workers to perform visible tasks rather than giving them time to think, which is essential for their roles.
Good ideas often come during moments of relaxation, such as in the shower, on a walk, or while commuting, rather than during formal work time.
Both Einstein and Mozart found that their best ideas came during moments of leisure, such as long walks or traveling, rather than during formal work sessions.
Knowledge workers should be judged by their outcomes, not by the visibility of their process, as much of their productive work happens internally and may appear 'lazy'.
The most productive work you can do often looks like the laziest -- but it can be hard to accept that because of how the workplace has changed over the last 100 years.
