Description: What if the thing you call work ethic is actually working against you? For years, Kelly Siegel treated sleep like a weakness. Four or five hours a night, caffeine, stress, and nonstop work became a badge of honor. He thought he was sacrificing sleep for success. Instead, he was starving the very system his business, body, and relationships depended on. In this solo episode of Harder Than Life, Kelly gets brutally honest about what years of poor sleep cost him—from a short temper and reactive decisions to anxiety, exhaustion, and chaos. He shares what changed when he stopped relying on willpower and built a sleep system he could actually maintain. The biggest lesson?  Exhaustion isn't a badge of honor. It's data. If you've been wearing your short nights like a medal, what do you think your body is trying to tell you?
