I've tried every productivity system out there—GTD, Pomodoro, time blocking—and after a year of tracking my output, the only thing that actually moved the needle was cutting my workday from 9 hours to 6. We treat productivity as if it's about squeezing more into each hour, but the data from my own experiments suggests the opposite: shorter hours force sharper focus and reduce the busywork that pads a typical day. Yet my colleagues think I'm crazy, and they point to their 10-hour days as proof of commitment. So, is personal productivity really about doing more in less time, or have we confused activity with results?
