Josh Jung – 15 Years of Mental Training | From Overlooked to MLB All-Star & World Series Champion

In this episode of The Mental Performance Mastery Podcast, Brian sits down with 2024 MLB All-Star and World Series Champion Josh Jung of the Texas Rangers.

Josh shares his journey from being undrafted out of high school to becoming a College All-American at Texas Tech, a 1st round draft pick, an MLB All-Star, and a World Series Champion — and the 15 years of intentional mental training that fueled that rise.

This conversation goes far beyond talent. It’s about preparation, discipline, and building a championship mindset long before the spotlight arrives.

In this episode, Brian and Josh unpack:

• Advice for athletes who feel overlooked or underestimated

• The importance of a daily routine and personal standards

• Using mental imagery and visualization to prepare for success

• The power of journaling for clarity and growth

• Why he uses concentration grids to sharpen focus

• Keeping a quiet mind under pressure

• Talking to yourself instead of listening to self-doubt

• The 3 keys he uses to “keep it simple”

• How Stoicism and reading have strengthened his resilience

• Building awareness around sleep, recovery, and readiness

This episode is a masterclass in mental resilience, work ethic, preparation, and performing at your best when it matters most.
