Years ago, Diane sat across from a brilliant executive who had every credential you’d want on paper. A sharp strategist. A fast decision-maker. Respected by the board.
And yet something was missing.
It wasn’t skill. It wasn’t experience. It was what Diane has come to call mental discipline—the capacity to shift mindsets, hold paradox, and lead confidently when the ground keeps moving underneath you.
That distinction is at the heart of a recent conversation Diane had with Authority Magazine, where she was asked a question that comes up often in her work: What actually separates good leaders from exceptional ones?
Her answer went somewhere she doesn’t always get to go in a two-minute conversation, into personal mastery, why humility is only possible after self-mastery, and why arrogance is usually a mask for something else entirely.
For leaders navigating transformation right now, and most are, there’s something in this conversation worth sitting with.
