| Red Lines: Humility vs. Narcissism and Integrity | 1 | 3 | 1 | 1 | Harry asks where extreme drive flips into toxic behavior. Max outlines his leadership framework around narcissism versus humility and explains why breach of integrity is an irreversible red line. | |

| The Reality of Hiring: A Players vs. B Players | 3 | 4 | 2 | 4 | Harry challenges the conventional wisdom that companies can only hire 'A players' at scale, labeling the claim absurd for large organizations.
