What if confronting fear is the best way to find peace, purpose, and growth? In this special episode, Marcus reconnects with his longtime friend William Robertson—a painter, architect, and entrepreneur known for designing his own fire-resistant home and embracing sustainability long before it was trendy. Their friendship, like a river ride, flows naturally between ideas, challenges, and laughs.

William shares what led him to fight a 19-year-old in a Muay Thai match at age 48, and how facing discomfort—whether through martial arts, fasting, or microdosing—has shaped his resilience and deepened his presence. Together, they reflect on personal growth, physical health, business leadership, and why pushing limits in any form makes life richer. This episode is both a celebration of curiosity and a call to keep evolving—on your own terms.
