A study was recently published in the Psychological Review about efficiency at work. Dr. K. Anders Ericcson studied the way musicians trained, and how long they trained, and compared their focus to their efficiency. The conclusion is that 80% of our outputs come from 20% of our inputs. And that working focused for 4 hours is more efficient than working unfocused for 8 hours. Otherwise said, this study advises us to be more focused for short periods in the day, and allow ourselves to rest: answer less phone calls, check emails less frequently and leave work early. Want to improve your work? Be ready to leave office early!
