John Baker has spent most of his life figuring out what allows people to perform when things get hard.
He played professional baseball for more than a decade, reaching the Major Leagues with the Marlins, Padres, and Cubs before eventually moving from the field into coaching, mental skills, player development, and performance psychology. His career would ultimately take him from being an MLB player to helping build and lead performance systems responsible for hundreds of professional players and coaches.
But this conversation goes well beyond baseball.
John and I originally met years ago on the jiu-jitsu mats, and that shared background became the jumping-off point for a much bigger conversation about why some of us are drawn toward difficult things in the first place.
We talk about the strange trust that exists between two people trying to choke each other unconscious, why shared suffering creates some of the strongest relationships in our lives, and what jiu-jitsu, professional baseball, military environments, and ultrarunning unexpectedly have in common.
We also get deep into performance psychology: visualization, attention training, managing arousal under pressure, learning to become the observer of your own thoughts, and why the popular definition of "mental toughness" might have very little to do with simply being willing to suffer more.
John's definition is much simpler:
Mental toughness is the ability to pay attention to the right thing, at the right time, regardless of the circumstances.
We unpack what that actually looks like when you're standing at the plate in a Major League Baseball game, stepping onto a jiu-jitsu mat, or trying to keep moving forward 100 hours into a 250-mile race.
This is a conversation about performance, but even more than that, it's about deliberately choosing difficult things, understanding what you value, and learning how to keep showing up.
