Joe describes burnout through three interconnected lenses. Physiologically, the adrenal system expands under sustained stress until it depletes — first compensated by caffeine, then collapsing into depression. Psychologically, living in constant “should” and “have to” mode creates a perpetual fight-or-flight state. Emotionally, running from unfelt feelings generates chronic adrenaline that eventually exhausts the system.

The key insight is that burnout isn’t caused by hard work itself, but by the adrenaline that drives the work. Some people thrive in intense environments while others burn out in seemingly easy ones — the difference is their internal relationship to what they’re doing. CEOs who sell their companies often spend years in pajamas because the sustained adrenaline output has completely depleted them.

“The burnout cycle is if you’ve been running on adrenaline for your anxiety for an extended period of time then typically eventually you’re going to burn out.”

The cycle is self-reinforcing: as you burn out, you see things more pessimistically, which increases fear, which burns more adrenaline. Brett describes how he used extreme sports to “burn off” accumulated background fear — a temporary fix that reveals the underlying pattern.
