This week's conversation is about performance. More specifically, it is about the ins and outs of steady progress and growth. My guest is Brad Stulberg who coauthored the book Peak Performance, which combines research from many fields into a description of how athletes, creatives and others continue to push boundaries in their respective crafts. As someone who is intermittently lazy, the growth equation framework that Brad and I explore has impacted me often since I first read the book several months ago. I hope you enjoy this conversation, which isn't about investing, but which is, at its heart, still about the power of compounding.    Books Referenced Outliers: The Story of Success Peak: Secrets from the New Science of Expertise   Online References Jool Health   Show Notes 1:32 – (First question) – How Vick Stretcher influenced the book, Peak Performance 4:32 – Looking at some of the preliminary research at the science of purpose 7:58 – The idea of a growth equation and the components that can lead to success 11:47 – How the introduction of stress can help in all sorts of creative and entrepreneurial pursuits. 13:39 – The ratio between physical and mental as an impact on this formula 14:56 – Just manageable challenges and the role that they play in the growth equation 18:06 – The idea of just manageable challenges through the example of an athlete 22:19 – Favorite example of a crazy feat of physical performance, stress on older athletes operating at high levels 23:30 – Thoughts about outside influences like mentors/coaches and how they help high performance individuals advance 25:51 – Describe catabolic and anabolic states and why anabolic is so important 29:13 – How the relationship of catabolic and anabolic states also helps the mind 30:47 – How does the idea of practice play into the growth equation 32:49 – Exploring the nuances of practice and why you don’t go all out             32:56 – Outliers: The Story of Success 33:00 - Peak: Secrets from the New Science of Expertise 34:24 – The idea of designing of a day 42:06 – What role can environment play on us 43:40 – How far is it healthy to run 46:25 – How does ego play into all of this 48:06 – The idea of camaraderie and study of Air Force Cadets highlighting this 49:28 – Fatigue and why it is believed to happen in the mind and not the body 54:00 – Most memorable day 55:43 - Method for finding purpose             56:29 – Jool Health 58:26 – Kindest thing anyone has ever done for Brad   Learn More For more comprehensive show notes on this episode go to http://investorfieldguide.com/brad For more episodes go to InvestorFieldGuide.com/podcast.
