"Recently, the Draugiem Group, a social networking company, added to this growing body of research. Using the time-tracking productivity app DeskTime, they conducted an experiment to see what habits set their most productive employees apart. What they found was that the 10% of employees with the highest productivity surprisingly didn’t put in longer hours than anyone else. In fact, they didn’t even work full eight-hour days. What they did do was take regular breaks. Specifically, they took 17-minute breaks for every 52 minutes of work."
