"Four Hours" refers to a popular time management concept that emphasizes the idea of maximizing productivity within a limited timeframe. It suggests that individuals can achieve significant results by focusing their efforts on essential tasks for just four hours each day. This approach encourages prioritization and efficiency, allowing for a better work-life balance. The concept is often associated with Tim Ferriss, who popularized it in his book, "The 4-Hour Workweek." Ferriss advocates for automation and delegation to minimize time spent on less important activities, ultimately leading to more free time and personal fulfillment.
