The One Skill That Changes Everything: Why Breath Is Your Ultimate Superpower Last week, I got to "roll" with my teacher—and I'm being very, very liberal with the term "roll" here. My instructor is Gutemberg Pereira, a 31-year-old literal world champion who's 6'4" and cuts down to 220 pounds when competing. Compared to my 5'2", 120-pound frame, even him giving me his back is an exercise in futility. But I'm always grateful for the opportunity to embarrass myself with him. It's an exercise in humility and resilience that I apparently still need. Anyway, last week I was the odd man out when it came time to roll, so Berg told me to partner with him. I lasted all of about three minutes in our five-minute round. And that's with Berg not even "attacking" me on ANY level—he was just being a body for me to try stuff on. Granted, a very big body for someone my size. As I sat there gasping for air like a fish out of water, Berg shared something that completely reframed how I think about performance, stress management, and life itself. He told me about the physiological way to calm down, have more energy, and reduce stress: two big inhales followed by one LONG exhale. And the whole time I'm rolling, I should be breathing through my nose, not my mouth. "If you find yourself breathing through your mouth," he said, "stop and catch yourself. Use it as a signal to slow down." Sitting there, wheezing and embarrassed, I realized I'd been handed one of the most fundamental lessons in human performance—again. The Lesson I Keep Forgetting As Berg spoke, I was transported back over 30 years to my early days training in Hapkido under Bong Soo Han. The same emphasis on breathing.
