Many people believe that working to the maximum is the secret to success，but research has found that moderation （適度） also gets results on the job.
   In a study led by Ellen Langer of Harvard University，researchers asked people to translate sentences into a new made-up language.Subjects who practiced the language moderately beforehand made fewer errors than those who practiced extensively or not at all.High levels of knowledge can make people too attached to traditional ways of viewing problems across fields — the arts，sciences，and politics.High conscientiousness is related to lower job performance，especially in simple jobs where it doesn't pay to be a perfectionist.
   How long we stay on the clock and how we spend that time are under careful examination in many workplaces.The young banker who eats lunch at his desk is probably seen as a go-getter，while his colleagues who chat over a relaxed conference-room meal get dirty looks from the corner office. "People from cultures that value relationships more than ours does are shocked by the thought of eating alone in front of a computer"，says Art Markman，a professor of psychology at the University of Texas，Austin.Social interaction has been shown to lift mood （情緒） and get people thinking in new directions and in ways that could help improve any post-lunch effort.
   Markman also promotes off-task time. "Part of being a good thinker is experiencing things that are seemingly unrelated to what you are working on at the moment but give you fresh ideas about your work，" he says. "Also，there is a lot of research showing that a positive mood leads to higher levels of productivity and creativity.So，when people do things to increase their life satisfaction，they also make themselves more effective at work."
