"Measure life enjoyment, not just productivity Dubner observes that success becomes a trap when it is its own metric. He noted that "success is intoxicating and makes you want more of it, which can come at the expense of loved ones" and that "finding the balance between productivity and happiness is hard because we focus on measurable numbers rather than overall life enjoyment." The fix: add a non-numeric metric — how often did you laugh, feel present, or help someone who didn't ask — to your weekly review.
