What Phil Knight's Shoe Dog taught me about belief, grit, and why your wildest goal is worth every round.

It starts as a whisper. A quiet, nagging thought that most people would dismiss as absurd. A “crazy idea.”

Maybe for you, it was the first time you seriously thought. I can be a champion. Not just a participant. Not just someone who trains for fun. A genuine, top-tier fighter. Or maybe it's the dream of building something, mastering a skill, pushing your body and mind somewhere you've never been.

This week, I've been reading Shoe Dog. The memoir of Nike founder Phil Knight. And I couldn't stop thinking about how his entire empire started with exactly that kind of thought. One that most people would have laughed at.

He flew to Japan with no real plan, bluffed his way into a meeting with a shoe manufacturer (Onitsuka Tiger), and secured the distribution rights for the United States. He came home and started selling shoes out of the trunk of his Plymouth Valiant at local track meets. That was the birth of what would become Nike. Knight wasn’t a slick salesman. In fact, he was an awkward, shy accountant. So how did he sell those first shoes? He wrote:

That hits home, doesn't it? In the ring, you can't fake it. You can't sell a feint you don't believe in. You can't project confidence you haven't earned. The opponent, the judges, the crowd. They all sense it. True belief in your preparation, your game plan, and your own ability is the most powerful weapon you carry into that ring. It is, as Knight put it, irresistible.

Knight's journey was not a clean, straight line to success. It was chaotic, desperate, and constantly on the verge of collapse. His first offices were so run down that employees dealt with a steady rain of pigeon droppings from the floor above. They were perpetually on the edge of bankruptcy, fighting lawsuits and betrayals from every direction. But one of the most powerful stories in the entire book is about Bill Bowerman, Knight's co-founder and legendary University of Oregon track coach. Bowerman was obsessed with building a better, lighter, grippier running shoe. He spent years tinkering, experimenting, failing. Then one Sunday morning, staring at his wife's waffle iron over breakfast, something clicked.

He poured liquid urethane into the iron, instantly ruining it. He bought another one and tried again. Failed again. He kept going. adjusting, experimenting, and refusing to accept that it couldn't be done. Eventually, he created the prototype for the revolutionary waffle sole that would define Nike's early identity and change the running shoe industry forever. He didn't get it right the first time. He didn't get it right the second time either. But he was obsessed with that 1% improvement, with finding the edge that nobody else had seen.

This is the grind of a fighter. It is never just about the knockout blow. It is about the small adjustments in your footwork, the subtle shift in your head movement, the new combination you drill a thousand times until it becomes second nature. It is about finding your own waffle iron, that small, unconventional tweak that gives you the edge over everyone else in your division.

Phil Knight often quotes a teacher who spoke of the pioneers who crossed the Oregon Trail: "The cowards never started, and the weak died along the way. That leaves us."

That is the spirit of a fighter. The road to greatness in boxing is a lonely one, littered with setbacks, injuries, self-doubt, and days when the gym feels like the last place you want to be. Many people have the crazy idea. Few have the resilience to stay in it long enough to see it through. They stop tinkering. They stop believing. They give up somewhere in the middle rounds.

But that's not you. You're still here. You're in the 12th Round.

This week, take these three things into your training:

This is what the 12th Round is about. Every week, we come back to this. Stories that matter. Lessons that translate from the page to the gym floor, from the boardroom to the ring. Real talk on boxing, performance, and what it actually takes to build something. Whether that's a career, a body, or a mindset that doesn't quit.

Phil Knight didn't build Nike in a week. Champions aren't made in a single session. But every great story has a starting point, and this week, you've taken another step.

This is what the 12th Round is built on.

Stay in it. Stay curious. And keep showing up. Because that alone puts you ahead of most.

Belief isn't just a feeling. It's a practice. Every morning, before you touch your phone, take 5 minutes to write down:

1. Three things you're grateful for. ("My health." "The chance to train today." "A supportive coach.")
2. What would make today great? ("Nailing that new combination." "Pushing through my roadwork." "Eating clean all day.")
3. One daily affirmation. ("I am a champion in the making." "My hard work is paying off.")

It sounds simple, but starting your day with gratitude and intention is exactly how you build the unshakable belief we've been talking about. Try it for a week. See what happens.

Until next week, stay in the fight.

This week’s newsletter comes from my desk at home. It’s the 1st of March, and I’ve just turned the last page of Shoe Dog by Phil Knight. I put it down and sat there for a minute. it hit differently than I expected. Not a business book. Just one man’s honest account of doubt, chaos, near collapse, and a stubborn refusal to quit. Knight didn’t have a plan. He had a belief. And he kept moving. That’s what shaped this edition, a genuine reminder that the path you’re on is worth staying on, even when it’s slow, even when it’s messy, even when no one else can see what you’re building yet.

This one’s for the fighters still in the early rounds.. Keep going!
