Phil Mickelson just won the PGA Championship at age 50. That is no joke. In this episode of the Growth Equation podcast,  Brad and Steve use Mickelson's shocking victory as the basis for a  conversation on aging and performance. They discuss the importance of mindset and intrinsic drive; how to thwart the decline of raw talent that comes with aging while at the same time reaping the rewards of wisdom; Mickelson's intense fasting regime (what exactly was it and did it help, hurt, or not really matter at all?); and how hard work isn't always about training the body but also about training the mind. This episode is chock-full of wisdom and practical advice. We hope you learn as much as we did from the discussion.
