Today, we're replaying my episode with Nik “The Carny” Lentz. It's not every day you talk to a UFC fighter turned trader. And this conversation is both intense and insightful. We start by talking about Nik's journey from a difficult childhood to a UFC career and his philosophy on fighting, parenting, and life. We then cover his move to trading derivatives full-time and his approach to position sizing, risk management, and more. This is a different kind of episode, but one I thoroughly enjoyed listening back to, and I hope you feel the same.
