Why 99 Percent Effort Equals Zero

The Playbook With David Meltzer

In today’s episode, I sit down with Vitor Belfort, the youngest champion in UFC history, whose journey extends far beyond the cage. We talk about the foundation of his success—faith, family, and values—and how protecting his marriage has been the greatest gift he could give his children. Vitor explains why 99 percent effort equals zero, the mindset that pushes him to always reach for that final percent, and how losses become lessons when lived through principle instead of feelings. From discipline in sport to discipline at home, Vitor shows what it means to truly be a champion in life.
