In 2017, former schoolteacher Jeff Horn walked into Brisbane’s Suncorp Stadium as the underdog and left as WBO world welterweight champion after defeating Manny Pacquiao in front of 51,000 fans.

But the fight is only part of Jeff’s story.

In this episode of the Mastering Podcast, Jeff opens up about being bullied as a child, discovering boxing at 18, and meeting the coach who told him he could become a world champion before almost anyone else could see it, joining our hosts, Don Sanka, Magnus Olsen, and Ryan Edwards. He takes us inside the pressure, focus, and self-belief that carried him into the biggest fight of his life—and explains how quickly everything changed when his hand was raised.

Jeff also speaks candidly about defeat, underestimating opponents, public criticism and the identity shift that followed retirement. Today, his focus has moved from winning belts to helping young people through Bullyproof Australia and the AMAYDA program.

This is a conversation about what hard work really looks like, why belief must be earned, how to respond when life does not go your way, and what it means to build a legacy bigger than your greatest achievement.

- Why Jeff chose boxing after starting at 18
