Andrew and Brad discuss how to “solve the puzzle” of transitioning gracefully through major shifts in career or life. In the athletic world, many struggle on the occasion of retirement because the intensity of competition and attention is difficult or impossible to match in more traditional career pursuits. A process-oriented mindset is urged, so that self-esteem is not attached to results or one’s identity as an athlete, or a career achiever as well. Another suggestion is finding new passions—they don’t necessarily have to be competitive—but something that lights you up and engages you deeply. More discussion of how to balance career, family, fitness/health, and personal goals, and how sometimes we look at health and fitness pursuits as “sacrifices” when in fact not doing healthy behaviors is the real sacrifice. Enjoy a thoughtful show full of practical tips from Andrew and Brad.
