I’d choose Warren Buffett. Everyone studies his investment philosophy, but what fascinates me more is his governance discipline – decades of consistently choosing management teams he trusts, staying out of their way, and still holding them accountable to shareholder interests. I’d want to ask him how he tells the difference, sitting across from a CEO, between confidence and integrity, because that judgment call sits at the heart of every board decision I make. He’s made that distinction correctly for over half a century, largely without spectacle, and I’d genuinely want to understand how he actually does it.
