I looked it up. The Sagebrush Oracle appears to be right! The probability of a full-time worker being fulfilled in life if they’re unfulfilled at work is 2%, according to research (Aaron Hurst and Nicole Resch, “2019 Workforce Purpose Index: Pathways to Fulfillment at Work,” Imperative, 2019). For more on the relationship between meaningful work and personal wellbeing, check out chapter 3 of Do Good at Work.
PS: If you have any questions for The Sagebrush Oracle, send them my way! I’ll ask as I shuffle by it on my trail runs.
