The humid, salt-heavy air at the Fort Lauderdale marina sat in my chest like a weight as I stepped out of the chilled black SUV.

I was thirty-four, founder and CEO of Sentinel Dynamics, a global cybersecurity and smart-infrastructure company. My life ran on eighty-hour weeks, airport lounges, lukewarm coffee, and the constant pressure of responsibility. My marriage to Ryan had slowly turned into one more failing operation I kept trying to stabilize long after the system was already compromised.
