Warren Buffett—the Oracle of Omaha, America’s favorite billionaire grandpa, and unofficial CEO whisperer—finally announced his retirement last week. Sure, the financial world went into a “what-happens-next?” frenzy, but here at The Core, we’re more interested in what he’s left behind.
CEOs from across industries shared what Buffett had taught them directly, including embracing brutal honesty about business challenges (thanks for the tough love, Warren), slashing unnecessary corporate fluff (bye-bye PowerPoint marathons), and hiring people with integrity first—because without integrity, intelligence, and energy, your business simply sinks.
Maybe his best advice of all? Stay humble, curious, and always overdeliver with simplicity. Let’s face it: Buffett may have retired, but good advice never expires.
