You can run multi-million dollar business operations, but if you can't sit still and be present at your own dinner table, your system is failing. Many high-performing executives get trained to operate under relentless corporate stress, but no one ever teaches them how to down-regulate their nervous system and return home to their families.

In this deep-dive podcast episode, Zac Armstrong sits down with retired Navy SEAL Commander Jon Macaskill to unpack the psychological, physical, and leadership realities of high-stress performance over a 24-year military career.

Key topics covered:
The hidden cost of executive stress on marriages and family life
How Jon lost his first marriage to the SEAL teams—and what he learned from it
Why box breathing and breathwork are tactical performance tools, not "hippy" fluff
How down-regulating the vagus nerve signals safety to the brain in 60 seconds
Shifting from "Mental Illness" stigma to proactive "Mental Fitness"
The power of saying "I screwed up" to build high-trust team cultures
"Choose Your Hard": Why aging and physical decay are choices you make
