“The longer you work, the less efficient you are,” said Bob Kustka, the founder of Fusion Factor, a productivity and time-management consulting firm in Norwell, Mass. He says workers are like athletes in that they are most efficient in concentrated bursts. Elite athletes “play a set of tennis, a down of football or an inning of baseball and have a pause in between,” he says. Working energy, like physical energy, “is best used in spurts where we work hard on a few focused activities and then take a brief respite,” he says.
And those respites look an awful lot like wasting time.
