You don't get to choose what you believe. That's the standard line on confidence, stated as law by the biggest podcast in this space. Markus Kaulius disagrees, and he's got a $170M company to back it up.
I sat down with him right after his daughter closed out a room of authors at Book Thinkers 2026. Markus built Magnum Nutraceuticals from nothing and wrote the USA Today bestseller Play a Bigger Game. He decided he was a confident man before he had a single reason to believe it, then did the work that made it true.
We get into the mentor he chose before that mentor ever knew his name, the filter he uses to decide who's allowed to influence him, and the one rule he swears by for actually becoming who you say you want to be. If you've ever waited for proof before letting yourself believe something about who you are, this one's for you.

🎙️ About Jack:
I moved to France alone at 16, started my first business at 17, and launched this podcast because I kept meeting people who had the answers to questions I didn't even know I was asking. My philosophy: you can set massive goals while being deeply fulfilled right now. That's the duality of gratitude and ambition.
